Leela the one-eyed cat has severe anxiety disorder and was peeing everywhere. She's on Prozac and that helped, but when she started hurting herself to get to Bunny, my husband and I realized that Bunny has become Leela's therapy dog. Voila, peeing stopped, self-injury stopped, and she's still an asshole but not as badly as before. They have their own room and sleep in it together at night or when unattended. This is how they sleep. Unless they're spooning.
