I know cats are solitary by nature but will socialize if they choose to. Hootie and Sissy generally sleep in the living room where my husband and I spend the most time at home. There are times though when Hooite will go and sleep at the end of the hallway farthest from the living room and Sissy with go sleep in the bathroom on the bath mat. I know it's probably no big deal but I can't help but worry a tad that they don't feel well or are depressed or something.
