We just adopted two rescue kittens on Monday. They're so funny, when I go in to clean their litter box they trot up behind me and sit in it until I go away. If I can get them distracted (with breakfast or dinner, depending on the time!) I clean it out really quickly, and when they realize what I'm doing they wait behind me until I'm done, then go immediately to it and use it, as if to restake their claim
