    }
}

Progress:

• Setup animation timing - Define frame rate (60fps) and step duration (0.6s per step)
• Create paw lift cycles - Use sine waves with phase offsets for natural gait
• Add subtle body sway - 2-3 pixel horizontal movement per step
• Implement paw placement - Slight curve inward on landing, splayed toes
• Apply easing functions - Ease-out for paw lifts, ease-in for placement
• Add secondary animation - Tail swish, ear twitches, whisker movement

Gait Pattern Implementation

1. Walking Gait - Diagonal pairs move together (front-left with back-right)
2. Step Timing - 600ms per full step cycle
3. Paw Phases:
   • Lift: 0-150ms (ease-out cubic)
   • Forward: 150-300ms (linear)
   • Lower: 300-450ms (ease-in cubic)
   • Ground: 450-600ms (static)

Example 1: Idle Sitting Cat Input: Cat in sitting position, occasional movements

CSHARP
float breathCycle = MathF.Sin(timeElapsed * 1.5f) * 2f;
float tailSwish = MathF.Sin(timeElapsed * 0.8f + 1.2f) * 15f;
DrawCatBody(canvas, baseY + breathCycle, tailAngle: tailSwish);

Output: Gentle breathing motion with periodic tail movement

Example 2: Prowling/Stalking Input: Slow, cautious movement with low body posture

CSHARP
float prowlSpeed = 0.3f;
float bodyLower = 8f; // Crouch lower
float pawLift = MathF.Max(0, MathF.Sin(stepCycle * prowlSpeed)) * 4f; // Smaller steps

Output: Deliberate, silent movement with minimal paw lifting
