✅ It’s a happy habit left over from kittenhood

But why?

Neonatal kittens knead their mother’s mammary glands to stimulate milk flow, and the motion wires itself to comfort. Adult cats re-trigger that association on soft, warm surfaces — blankets, laps — often while purring. Many also suckle fabric or drool, completing the kitten-time memory. It’s one of the clearest ‘baby behavior kept forever’ traits in pets.

🧒 For younger kids: Kittens push paws to get milk. Big cats still do the push-push when they feel cozy and safe!

🤯 Wow fact: Kneading cats sometimes drool too — both are leftover kitten feeding behaviors switching on.

Good guesses kids make

“To sharpen their claws” — Claw-sharpening is scratching posts — kneading with soft paws is comfort, not maintenance.

“To make a nest before sleeping” — Fluffing a spot happens too, but the paw-push rhythm comes straight from kitten milk time.

“Because their paws itch” — Itchy paws get licked or bitten — the slow push-push-push is pure contentment.
