I tried leaving my tshirt in AprilLoves crate when she was small to give her comfort (she was gated in the kitchen with crate open, food and litterbox). Well, the first few weeks she was very mad when I left!!! She kept peeing on my clothes!!! lol. So I stopped doing that and just made sure she had plenty of toys and such. Now she loves going through my laundry and has no problems with me leaving because she knows I always return
