What do your cats do all day?
My almost 3 year old runs out as soon I open the door and then I only see him when he catches something or comes back, walks in, meows, looks around and leaves to dinner. Once locked in, torture Mama cat.
3-6 year old (really no idea) goes out in morning, back in soon for kitty massage, sleep around me, go out short time, back in, lay around, get brushed, eat, out, and when locked in run from Blanco and ask to go in the garage. She sleeps in my car now.
Not a lot of playing - seems like you all have a lot more active cats.
