 Kittens that were able to observe their mothers performing an experimentally organised act were able to perform the same act sooner than kittens that had observed a non-related adult cat, and sooner than the ones who, being placed in trial and error conditions, observed no other cat performing the act.Even though cats will occasionally reach up with a paw to put a person's hand on the exact spot where the cat wants to be scratched, or stretch up to indicate they want a door opened that they cannot reach or turn without opposable thumbs, behaviours they would likely have to learn through observation, social interaction, and accumulated experience even without being trained by humans specifically to perform these tasks, these behaviours have mainly been discussed anecdotally, and more studies would be needed before researchers can conclude how developed the cats' theory of mind may be.The term copycat comes from popular belief that cats, in an extension of their instinctual tendency to copy each others' stalking, pouncing, chasing, and wrestling to improve their hunting skills, will follow any sufficiently enticing movement by a familiar cat, human, or other accustomed nearby nonthreatening animal.
