Kitten Behaviour refers to the repertoire of gestures — nuzzling, kneading, purring, batting, curling, arching, watchful stillness — that many Kittens draw on when expressing their persona. Behaviour is highly personal and varies from Kitten to Kitten.

As Kitten Play matured, community writing and events helped articulate a shared but non-prescriptive vocabulary of behaviour.

There is no correct set of Kitten behaviours. Some Kittens are highly expressive; others are subtle. Communities generally treat variation as a strength.
