I think Lloyd (aka: Bear) sometimes forgets that there are other rooms in the apartment besides the living room and bedroom. He seems to rediscover the bathroom every few weeks and tours it as though he has never been in there before. Lloyd is really intrigued by water; he often jumps up to the sink after the water has been running. Shawn used to give him baths and Lloyd never seemed to mind much! Sylvester, on the other hand, runs away if the slightest bit of water touches him.
My parents used to have a cat that loved water, but I think it's usually a rare trait.
