Cat girls eat male adventurers. They lure their prey into secluded areas by swishing their tails, purring, giving themselves a completely adorable tongue bath, rubbing against their victim's legs (always whilst purring), and singing the Meow Mix theme song. Once the victim is led away from the party and seduced by the extreme unrivaled cuteness of the cat girl, she doesn't eat them yet; she first uses the victim as a scratching post (possibly does some interesting stuff before that), tears them to kibbles and bits, coughs up a hairball or two, sucks out the victim's liver through a "straw", and orders a pizza. Then she devours her victim and takes a nap.
