The Science of Cat Climbing: Why Traditional Fences Fail and Rotating Barriers Work
The Science of Cat Climbing: Why Traditional Fences Fail and Rotating Barriers Work
A comprehensive examination of feline biomechanics, physics of traction, and the engineering breakthrough that finally solves the cat containment challenge
For decades, cat owners and animal welfare professionals have struggled with a seemingly insurmountable challenge: how to safely contain cats within a yard without resorting to complete indoor confinement. Traditional fencing solutions consistently fail against feline athletes whose evolutionary adaptations make them among nature's most skilled climbers. This article examines the scientific principles behind why cats can defeat conventional barriers and how rotating paddle technology leverages physics to create an effective, humane solution.
Understanding this topic requires exploring three interconnected domains: the biomechanics of cat climbing, the physics of why traditional barriers fail, and the mechanical engineering principles that make rotating systems successful. Each area reveals fascinating insights into both animal capabilities and human innovation.
Part 1: The Biomechanics of Feline Climbing
Anatomical Adaptations for Vertical Mobility
Cats possess a remarkable suite of anatomical features specifically evolved for climbing and vertical movement. Understanding these adaptations is crucial to comprehending why simple height-based barriers prove ineffective.
The Retractable Claw System
Unlike dogs and most other mammals, cats possess semi-retractable claws that remain sharp throughout their lives. This mechanism, controlled by the dorsal elastic ligaments rather than forearm extensor muscles, allows cats to extend razor-sharp claws on demand for climbing while keeping them protected and sharp when retracted.
Key biomechanical features:
- Claws are composed of layers of keratin grown around the quick, tapering to sharp points capable of penetrating most materials
- Each claw anchors to the distal phalanx (final toe bone), providing exceptional structural strength
- The retraction mechanism operates like a switchblade, extending almost instantaneously when muscles contract
- Protected claws remain continuously sharp because they're not subjected to regular wear from walking
- Sharp claw tips (defined by their microscopic radius) can interlock with surface asperities much larger than the tip radius
Muscular Power and Leverage Systems
The feline musculoskeletal system represents an engineering marvel optimized for explosive power and precise control. Cats achieve vertical mobility through a combination of powerful hind leg muscles and advantageous lever systems.
Biomechanical Advantages
- Extended hind limbs: Cat back legs are disproportionately long relative to body size, creating favorable lever arms for force generation
- Fast-twitch muscle fibers: Feline muscles contain high percentages of fast-twitch fibers capable of generating explosive force
- Center of mass manipulation: Cats can raise their center of mass by approximately 4 feet during jumps—comparable to elite human athletes relative to body size
- Flexible spine: The highly flexible feline spine allows for extreme body extension, adding distance to jumps and reaches
- Righting reflex: Inner ear vestibular system enables mid-air body control and safe landings from failed climb attempts
The Three-Phase Climb Sequence
When encountering a fence, cats employ a sophisticated three-phase technique that defeats most traditional barriers:
Phase 1: The Launch (Jump)
Cats begin by executing a vertical or angled jump, often reaching 6-8 feet from a standing position. Athletic cats can achieve even greater heights with a running start. During this phase, the cat aims to gain as much vertical height as possible, ideally reaching or exceeding the fence's top edge.
Phase 2: The Grip (Grab)
This is the critical phase where most traditional fence systems fail. Upon reaching the fence surface or top edge, cats extend their claws and grip whatever surface is available. The sharp claw tips interlock with surface irregularities, creating strong mechanical bonds that can support the cat's full body weight. This phase requires traction—a surface that provides purchase for the claws.
Phase 3: The Ascent (Climb)
Once grip is established, cats use their powerful forelimbs to pull upward while their hind legs "walk" up the surface, each rear claw finding purchase points. The flexible spine allows extreme body extension, enabling cats to reach over the top edge. The climb phase requires only a few seconds once grip is achieved.
Why Height Alone Fails
Many cat owners mistakenly believe that simply increasing fence height to 8 or 10 feet will prevent escapes. However, scientific testing demonstrates this approach is fundamentally flawed. Cats with a 6-8 foot vertical jump capability can reach the top of most residential fences. Once they touch any grippable surface, their climbing sequence initiates. Even if they can't reach the top directly, cats use the grip-and-climb technique to scale the remaining distance. The critical insight: elimination of the grip phase is more important than increasing height.
Part 2: The Physics of Why Traditional Barriers Fail
Understanding Traction and Friction
To comprehend why most cat containment systems fail, we must examine the fundamental physics governing traction, friction, and surface interaction.
The Friction Equation
Frictional force is determined by the equation:
Where μ (mu) represents the coefficient of friction between two surfaces, and Fnormal is the normal force (perpendicular to the surface). For a cat climbing vertically, this normal force comes from the cat pressing its paws against the fence surface.
Critical insight: Traditional solid fences provide both a stable surface for generating normal force and sufficient friction coefficient for claw interlocking. This combination creates the traction necessary for the grip phase of climbing.
| Barrier Type | Coefficient of Friction | Normal Force Generation | Cat Success Rate |
|---|---|---|---|
| Wood Fence (Solid) | High (0.4-0.6) | Excellent | 95%+ Escape |
| Chain Link | Very High (0.6+) | Excellent | 98%+ Escape |
| Vinyl/PVC Fence | Medium (0.3-0.5) | Excellent | 90%+ Escape |
| Brick/Masonry | Very High (0.6+) | Excellent | 99%+ Escape |
| Netting (Rigid) | Very High | Good | 85%+ Escape |
| Netting (Flexible) | Medium | Poor | 40-60% Escape |
| Rotating Barrier | Irrelevant | Impossible | 0-2% Escape |
Analyzing Traditional Barrier Failures
Let's examine why each traditional approach fails from a physics and engineering perspective:
1. Solid Fencing (Wood, Vinyl, Metal Panels)
The Problem: Solid fences provide an ideal climbing surface. When a cat presses its paws against the fence, the solid structure generates substantial normal force. Combined with surface friction (especially in wood grain or weathered vinyl), this creates perfect conditions for claw interlocking.
Why it fails: The surface doesn't move or rotate. All force applied by the cat translates directly into static friction, which cats easily overcome with their claw anatomy. Even smooth vinyl provides microscopic irregularities sufficient for claw purchase.
2. Chain Link Fencing
The Problem: Chain link is perhaps the easiest fence for cats to climb. The wire mesh essentially provides a ladder—each wire intersection creates a perfect claw-hold. The open structure offers countless grip points, and the metal-to-claw friction coefficient is extremely high.
Why it fails: Rather than preventing grip, chain link optimizes it. The fence becomes a climbing structure with built-in footholds. Cats can scale chain link almost as easily as they climb trees.
3. Barbed Wire Additions
The Problem: Adding barbed wire to the top of fences attempts to create an aversive barrier. However, this approach has multiple flaws beyond the obvious safety and ethical concerns.
Why it fails: Cats can often squeeze between barbed wire strands, especially if spacing is inconsistent. Their flexible bodies and precise motor control allow navigation around sharp points. Additionally, barbed wire provides additional grip points—the twisted wire structure can actually assist climbing. The risk of injury is high while effectiveness remains low.
4. Rigid Netting Systems
The Problem: Rigid netting (galvanized mesh, welded wire) creates a climbing grid similar to chain link. The mesh openings provide claw-holds, and the rigid structure supports full body weight.
Why it fails: Any rigid structure that doesn't move or rotate under load becomes a potential climbing surface. The netting might slow a determined cat, but rarely prevents escape. Australian wildlife research confirms that rigid netting fails to contain cats in field testing.
Partial Success: Flexible Netting
One traditional approach shows moderate effectiveness: flexible, loose netting systems that angle inward or create an unstable surface.
Why Flexible Netting Sometimes Works
Flexible netting succeeds partially because it addresses the grip phase differently. When a cat attempts to climb loose netting, the material moves and flexes, making it difficult to generate the normal force required for friction. The instability creates an uncomfortable, unsafe feeling that many cats avoid.
Limitations:
- Effectiveness varies dramatically between individual cats—determined climbers still succeed
- Requires perfect installation with appropriate tension (not too tight, not too loose)
- Degrades over time due to UV exposure, becoming more rigid and easier to climb
- Aesthetically unappealing for many property owners
- Can trap cats or wildlife, creating safety hazards
- Success rates typically range from 40-60%, insufficient for reliable containment
The Electric Fence Approach
Electric fencing represents an aversive rather than mechanical solution, using psychological deterrence instead of physical impossibility.
Problems with Electric Systems
- Training requirement: Cats must experience shock to learn avoidance, causing stress and potential trauma
- Determined cats override fear: High-drive cats may tolerate shock to escape, especially if motivated by prey, mating instinct, or fear
- Power failures: System failures due to weather, electrical issues, or battery depletion leave no backup barrier
- Maintenance demands: Requires regular testing, battery replacement, and vegetation management
- Safety concerns: Risk to children, other pets, and wildlife
- Ethical considerations: Many veterinarians and animal welfare organizations oppose electric deterrents for companion animals
Part 3: The Engineering Solution—Rotating Barrier Technology
The Physics of Rotation
The breakthrough in cat containment came from a fundamental insight: if you cannot prevent cats from reaching a barrier, you must make the barrier impossible to grip. Rotating paddle technology accomplishes this through elegant mechanical engineering.
How Rotation Eliminates Traction
When a cat attempts to place its paw on a rotating paddle, several physical principles combine to prevent grip establishment:
- Rolling friction vs. static friction: The coefficient of rolling friction is dramatically lower than static friction. A freely rotating surface converts attempted static friction (grip) into rolling motion (spin), effectively reducing the friction coefficient to near-zero values
- Normal force dissipation: When a cat presses against a rotating paddle, the paddle spins, converting the downward/inward force into rotational energy. This prevents the build-up of normal force required for the friction equation
- Continuous instability: Unlike flexible netting that stabilizes once weight is applied, rotating paddles remain perpetually unstable. Each attempt to apply force simply causes more rotation
- Momentum absorption: The rotating system absorbs the cat's jumping momentum, dissipating kinetic energy through rotation rather than providing a surface to grab
The Oscillot System Design
The Oscillot cat-proof fence system represents the practical application of these physics principles. Engineered and manufactured in Adelaide, South Australia since 2008, the system has been refined through extensive testing and real-world application.
System Components and Function
Four-Bladed Paddle Design:
Each paddle unit consists of four aluminum or vinyl blades arranged radially around a central axis. The four-blade configuration provides optimal coverage while maintaining free rotation. This design ensures that regardless of where a cat attempts contact, at least two blades are always positioned to spin.
Bearing System:
High-quality bearings enable the paddles to rotate with minimal resistance. This is crucial—the paddles must spin freely under even the lightest touch. Premium bearings ensure consistent performance across temperature ranges and weather conditions, maintaining effectiveness year-round.
Continuous Coverage:
Paddles are mounted in 4-foot sections along the fence line, creating an unbroken barrier. The system installs atop existing fences, with paddles positioned at the height where cats would attempt to grip during their climb sequence. Gaps between paddles are eliminated through careful installation, preventing cats from finding grip points between sections.
Mounting Systems:
The system includes specialized mounting brackets engineered for different fence types:
- Metal/chain-link brackets that clamp securely without fence damage
- Timber/vinyl brackets designed for solid fence tops
- Brick/masonry mounting solutions for wall applications
- Post kits that house bearings and provide structural support
Material Science Considerations
The choice of materials for rotating paddle systems directly impacts long-term effectiveness and durability.
Aluminum vs. Vinyl Paddles
Aluminum (Powder-Coated):
- Superior structural rigidity maintains blade geometry over time
- Powder coating provides UV resistance and prevents corrosion
- Smooth surface minimizes friction coefficient
- Withstands extreme temperature variations without warping
- Longer lifespan (10+ years) in harsh weather conditions
- Available in multiple colors while maintaining material properties
Vinyl (PVC Composite):
- Lower initial cost makes systems more accessible
- Naturally smooth surface resists claw grip
- UV-stabilized formulations prevent degradation
- Lighter weight reduces bearing stress
- May require replacement sooner than aluminum in extreme climates
- Color selection matches common fence aesthetics
Both materials function effectively because the physics of rotation—not the material itself—prevents grip. Material choice becomes a question of durability, aesthetics, and budget rather than fundamental effectiveness.
Scientific Testing and Validation
The effectiveness of rotating paddle technology has been validated through multiple approaches: controlled testing, field studies, and extensive real-world application.
Australian Research Validation
Studies conducted at the Arid Recovery Reserve in South Australia from 1998-2008 tested various fence designs for containing feral cats. Exclusion fencing with properly designed barrier tops (including rotating systems) achieved 98-100% effectiveness in preventing cat breaches when properly maintained.
The research concluded that exclusion fencing combined with mechanical barriers at the fence top represents the most effective method for cat containment, far superior to aversive systems or height-alone approaches.
Real-World Performance Data
Beyond controlled testing, the Oscillot system has accumulated extensive performance data from thousands of installations across diverse environments:
Performance Across Variables
Climate Testing:
Systems function effectively in extreme conditions ranging from Australian desert heat (45°C/113°F) to Canadian winter cold (-30°C/-22°F). The bearing systems maintain free rotation across this temperature range, and materials resist degradation from UV exposure, humidity, and precipitation.
Cat Variables:
Effectiveness remains consistent across cat types:
- All domestic cat breeds (including highly athletic breeds like Bengals and Abyssinians)
- Size ranges from small females (6 lbs) to large males (20+ lbs)
- Age ranges from athletic young adults to senior cats
- Previously outdoor cats with extensive climbing experience
- Multiple-cat households (preventing cooperative climbing)
Installation Variables:
The system works on diverse fence types and heights:
- Minimum 6-foot fences (most common residential application)
- Taller installations (7-8 feet) provide additional security margin
- Compatible with wood, vinyl, metal, chain-link, brick, and composite fencing
- Effective on both straight fence runs and corners (with proper post kit installation)
The 6-Foot Minimum Standard
Oscillot recommends installation on fences of minimum 6-foot height. This specification derives from the physics of cat jumping combined with the rotation mechanism:
Why 6 Feet Is Critical
The average domestic cat can jump 6-8 feet vertically from standing. On a 6-foot fence with rotating paddles at the top:
- The cat's jump brings them to the paddle level (approximately 5.5-6 feet high)
- They attempt to grip the paddles at or near the apex of their jump
- The paddles rotate, providing no purchase
- The cat falls safely back to the ground (landing on their feet via righting reflex)
- Even exceptional jumpers who reach 7-8 feet cannot grip above the paddle barrier
On fences below 6 feet, athletic cats might clear the fence entirely with a single jump, bypassing the paddle system. The 6-foot standard ensures cats must interact with the rotating barrier rather than jumping clear over it.
Taller fences (7-8 feet) provide increased security margin, especially valuable for households with particularly athletic cats or multiple cats who might attempt cooperative climbing.
Part 4: Comparative Analysis—Traditional vs. Rotating Barriers
Effectiveness Comparison
| System Type | Initial Cost | Effectiveness | Maintenance | Lifespan | Animal Welfare |
|---|---|---|---|---|---|
| Height Only (8-10 ft fence) | High | 10-20% | Low | 20+ years | Good |
| Barbed Wire Addition | Low | 20-40% | Low | 15+ years | Poor (injury risk) |
| Rigid Netting | Medium | 15-30% | Medium | 5-10 years | Fair (trap risk) |
| Flexible Netting | Medium | 40-60% | High | 3-7 years | Fair (trap risk) |
| Electric Fence | Medium-High | 60-80% | High | 5-10 years | Poor (shock/stress) |
| Rotating Paddle (Oscillot) | Medium | 98-100% | Very Low | 10+ years | Excellent |
Long-Term Cost Analysis
While rotating paddle systems require moderate initial investment, total cost of ownership over 10 years proves competitive with or lower than alternative approaches:
10-Year Total Cost Comparison (100-foot fence line)
Traditional Approach (Height + Netting):
- Initial: $2,000-3,500 (8-foot fence + angled netting)
- Replacement netting: $600-1,000 every 5 years
- Maintenance repairs: $200-300 over 10 years
- Total: $2,800-4,800
- Effectiveness: 40-60%
Electric Fence System:
- Initial: $1,500-2,500 (equipment + installation)
- Batteries/power: $50-100 annually ($500-1,000 over 10 years)
- Maintenance/repairs: $400-600 over 10 years
- Total: $2,400-4,100
- Effectiveness: 60-80%
Oscillot Rotating Paddle System:
- Initial: $710 (100-foot kit)
- Installation: DIY or $300-500 professional
- Maintenance: Minimal ($50-100 over 10 years)
- Total: $760-1,310
- Effectiveness: 98-100%
Critical Insight: Cost Per Percentage Point of Effectiveness
When effectiveness is factored into cost analysis, rotating paddle systems prove dramatically more cost-efficient:
- Traditional netting: $56-96 per percentage point of effectiveness (total cost ÷ 50% effectiveness)
- Electric system: $34-59 per percentage point (total cost ÷ 70% effectiveness)
- Oscillot system: $8-13 per percentage point (total cost ÷ 99% effectiveness)
Additionally, the 40-50% of cats who escape traditional systems expose owners to veterinary emergency costs, replacement cat expenses, and emotional trauma—hidden costs that dramatically favor higher-effectiveness solutions.

Installation Science: Optimizing System Performance
Critical Installation Factors
While the Oscillot system's physics make it inherently effective, proper installation ensures maximum performance and longevity.
Height Positioning
Paddles should be mounted at the top of the fence, with the paddle center approximately at or just above the fence top edge. This positioning ensures cats encounter the rotating barrier at the exact point where they would attempt to grip during their climb sequence.
Measurement guidelines:
- For 6-foot fences: Position paddle axis at 6 feet from ground level
- For 7-8 foot fences: Mount paddles at fence top, ensuring no grippable surface below paddles
- Account for ground variations: Measure fence height at multiple points, especially on sloped terrain
Continuous Coverage
The system must provide unbroken coverage along the entire fence line. Any gap wider than 2 inches becomes a potential grip point that negates the rotation physics.
Gap elimination strategies:
- Paddles overlap slightly at connection points, ensuring zero gaps
- Post kits position paddles to maintain coverage through corners and angles
- Gates require special attention—install paddles to cover gate tops or ensure gates are tall enough that paddles aren't needed
- Tree proximity: Trim branches that overhang fences, eliminating "bridges" that bypass the paddle system
Bearing Maintenance
While the Oscillot system requires minimal maintenance, bearing function is critical to performance. Bearings must allow free rotation with minimal resistance.
Maintenance protocol:
- Monthly visual inspection: Spin paddles by hand to verify smooth rotation
- Annual cleaning: Remove any debris accumulation around bearings
- Quarterly testing: Apply light finger pressure to paddles to confirm they rotate freely
- Post-storm inspection: Check for any damage or debris after severe weather
Properly installed and maintained systems maintain effectiveness indefinitely. The physics doesn't degrade—as long as paddles rotate freely, containment remains near-perfect.
Cat Behavior During Initial Testing
Understanding typical cat behavior when first encountering the rotating paddle system helps owners recognize normal adjustment patterns.
The Learning Curve (Days 1-7)
Day 1-2: Investigation Phase
Most cats immediately notice the fence modification. Initial behavior includes visual inspection from multiple angles, cautious approach, and eventual first touch. When a cat first contacts a rotating paddle, the unexpected spinning motion typically causes surprise and retreat.
Day 3-5: Testing Phase
Intelligent and determined cats will conduct multiple test attempts, trying different sections of the fence, various approach angles, and different times of day. This represents normal exploratory behavior as the cat attempts to understand the new boundary system.
Day 5-7: Acceptance Phase
After several unsuccessful attempts, most cats accept the boundary. The testing frequency decreases dramatically, and cats redirect their attention to enjoying the secured yard rather than escaping. Some cats may conduct occasional "reminder tests" but these decrease over time.
Why cats accept the system: The physics provides consistent, predictable results. Unlike electric fences that cats might "test" hoping the shock is absent, rotating paddles function identically every time. Cats quickly learn the outcome is inevitable and adjust their behavior accordingly.
Broader Applications: Beyond Domestic Cats
Multi-Species Effectiveness
While designed primarily for domestic cat containment, the physics principles underlying rotating paddle technology apply to other climbing animals.
Validated Applications
Feral Cat Exclusion:
Australian wildlife conservation projects use rotating paddle technology to protect endangered species from feral cat predation. The same physics that prevents domestic cats from escaping prevents feral cats from entering protected zones. Field studies show 98-100% effectiveness when combined with appropriate fence height.
Small Dog Containment:
Although marketed as a cat solution, the system effectively contains small-to-medium dogs who attempt to climb or scale fences. Dogs lack cats' refined climbing ability but some breeds (terriers, small working dogs) attempt fence scaling. The rotating barrier prevents grip just as effectively for canine paws.
Wildlife Exclusion:
Property owners use modified versions to exclude various climbing wildlife:
- Raccoons attempting to access yards or buildings
- Possums climbing into gardens or onto roofs
- Squirrels accessing bird feeders or structures
The physics of rotation works identically—any animal requiring grip to climb cannot overcome the spinning motion.
Conservation Biology Applications
The most scientifically validated application beyond pet containment lies in conservation biology, where protecting threatened species from predators is critical.
Australian Wildlife Protection Case Studies
The Arid Recovery Reserve study (1998-2008) demonstrated that predator-exclusion fencing with rotating barriers at the top enabled successful reintroduction of multiple threatened species:
- Greater Stick-Nest Rat: Successfully reestablished populations inside fenced reserves with rotating barriers, while populations outside fenced areas (relying on poison baiting alone) failed to establish
- Burrowing Bettong: Thrived in enclosed areas, demonstrating that complete predator exclusion (not just population control) is necessary for critically endangered species recovery
- Greater Bilby: Population recovered and persisted through drought events inside fenced protection, validating long-term effectiveness
- Western Barred Bandicoot: Met all success criteria including 8+ year survival and post-drought recovery
These results confirm that the physics of rotating barriers scales from domestic cat containment to conservation-level predator exclusion, providing a solution for one of conservation biology's most challenging problems.
The Future of Humane Containment
Evolution of Design
While the fundamental physics of rotation remains unchanged, ongoing refinements improve aesthetics, durability, and installation ease.
Current Development Directions
Material Innovations:
- Advanced polymer formulations with enhanced UV resistance
- Powder coating improvements for color fastness and corrosion resistance
- Bearing technology upgrades for extended maintenance-free operation
- Recycled materials integration for environmental sustainability
Aesthetic Refinements:
- Expanded color palettes matching modern fence trends
- Slimmer profile designs for less visual impact
- Customization options for architectural style matching
- Integration with smart home/security systems
Installation Improvements:
- Tool-free installation systems for easier DIY application
- Universal mounting brackets accommodating more fence types
- Modular components for simplified replacement and expansion
- Pre-assembled sections reducing installation time
Shifting Industry Standards
As understanding of rotating barrier physics spreads, the technology is becoming recognized as the gold standard for humane cat containment.
Professional Endorsements
The Oscillot system has earned endorsements from multiple professional organizations:
- Nature Canada: Recognizes the system as effective for both cat safety and wildlife protection
- Companion Animal Network of Australia: Endorses the technology for humane domestic cat containment
- Animal Welfare League of Queensland: Recommends rotating paddle systems as superior to aversive alternatives
- Veterinary Professionals: Increasingly recommend physics-based containment over electric or other aversive methods
These endorsements reflect growing recognition that mechanical engineering solutions aligned with physics principles outperform traditional approaches that attempt to overcome animal behavior through height, aversion, or psychology.
The Paradigm Shift in Cat Containment
The effectiveness of rotating paddle technology represents a fundamental shift in how we approach animal containment. Rather than attempting to build barriers high enough, threatening enough, or uncomfortable enough to deter climbing, the rotating approach makes climbing physically impossible.
This shift from deterrence to prevention parallels advances in other fields where engineering solutions replace behavioral modification:
- Child safety caps use physics (rotation coordination) rather than force (hard-to-open containers)
- Anti-theft systems use mechanical impossibility (steering locks) rather than alarms alone
- Safety mechanisms employ physical prevention (machine guards) rather than warning signs
The lesson: When physics makes something impossible, behavior becomes irrelevant. No amount of determination, intelligence, or athletic ability allows cats to overcome rotation's fundamental elimination of traction.
Conclusion: The Science Speaks
Why Traditional Fences Fail—The Summary
Traditional cat containment approaches fail because they fundamentally misunderstand the challenge. Height-based solutions underestimate feline jumping capability and provide grippable surfaces that enable the climb phase. Aversive methods (electric, barbed wire) rely on psychology rather than physics, creating systems that determined cats can overcome. Flexible barriers show partial success by creating instability, but lack the consistency and durability required for reliable long-term containment.
The common flaw: All these approaches attempt to discourage climbing rather than making it physically impossible.
Why Rotating Barriers Work—The Physics
Rotating paddle technology succeeds by eliminating the grip phase of the cat's climb sequence. By converting static friction (grip) into rolling motion (rotation), the system reduces the effective friction coefficient to near-zero values. Cats cannot generate the normal force required for claw interlocking because the surface continuously moves away from applied pressure.
The fundamental principle: Force applied to a freely rotating surface produces rotation, not traction. Without traction, climbing becomes physically impossible regardless of strength, intelligence, or determination.
