Pretty much ALL the time. He doesn't do ANYTHING but eat, poop, and sleep. He's between 7 and 8 years old. On occaision he will play with me or venture on the deck for maybe 5 minutes, or look out the window, but then it's back to sleep. Do cats get depressed? (we did move within the past 4 months)
I have another cat who runs around the house like a madwoman and attacks her own shadow, loves the stairs and while she gets her fair share of cat naps, she is very active. She is between 3 and 4 years old.
