I have two cats, and one of them has been doing something really weird. SHe lies down and hangs out in the litter box! She curls up in there and stays - regardless of whether it is clean or has #2 in it! It is really gross and I dont know what to do. This is a cat who is nervous and skittish as it is. We moved a few weeks ago, but she has been settling in just fine, and although she has done this occasionally in the past, she has been doing it all the time for the past few days. She is also hiding other places, like under the bed and in the cloest, when she's not in the box. We were just at the vet last week, so I don't thin she is sick. Help! I am worried about her, and also, it is really gross!
