Procedural Cat Generator

PROCEDURAL CAT GENERATOR
1000 CATS, 0 IMAGES — ALL CODE

No sprites. No PNGs. Just math.

Every cat is drawn live from a seed — layers of fur, tail, whiskers, ears, eye color, and pattern built with code. HSL color jitter, DNA string, and a custom renderer stacking shapes at 60 FPS.

What you get:

• Infinite unique cats from a single SEED
• Breeds & coats: tabby, calico, tuxedo, void (black), orange, smoke, point, kitten
• Traits: fur length, fluff, tail curl, whisker spread, eye hue, size
• Stats on screen: FPS, DRAWS / SEC, UNIQUE SEEDS, LAYERS, RENDERER
• Section: Math behind the meow — how the generator works
• Copy SEED, reroll, save — perfect for characters, icons, VTuber cats, game jam pets

Built as a single HTML file. Runs in browser, offline, no images to load. Pure generative toy.

Hit MEOW to reroll. Find the one that's yours.

DEVELOPER NOTES:

This build is entirely in HTML5 and based on a Unity prototype.
