The animal version of a gold digger, usually a cat, that only shows affection towards it's human master(s) when it wants food.
"Your bitch of a cat just scratched the shit out of me when I tried to pet her! Just 5 minutes ago it jumped on my lap and was acting like I was made out of catnip! I fed her, and now she acts like I'm the dog that raped her kittens!"
"Yeah, sorry. She's a total kibble-digger. Got what she wanted and moved on."
