I know that my bengals get bored of their toys and start getting into stuff they know they aren't supposed to. Especially if we haven't played with them enough. Every once in a while Ally will run up and bite us and then run off. It doesn't happen too often, but I have figured out she does it when she is really bored. Its like she is trying to get our attention. She even has a playmate that is a month younger than her, but nothing makes her happier than us playing with her. She is really loving afterwards. Bengals are very needy since they hardly sleep. My two are up from 6 a.m. until 11:00 p.m. with just a 2 hour nap at 1 in the afternoon. Its weird they are on a schedule like that, but that's how they have always been. They sleep all night of course. Anyway maybe keeping her stimulated with new toys and stuff. My max loves ice cubes. He gets them going fast on my would floor. I decided to get a bowl of water and put the ice in there (also tried it with ping pong balls), both those ideas were a hit and keeps them entertained for 2 hours. Bengals are funny cats, but are definitely for experienced cat owners. Good luck!
