Have you ever had a part time cat?
I have a cat who will run out of the house one day in the spring. All through summer she won't let me near her and will only eat when I'm well away from the food bowl; if I try to come near she'll run off. Then, come fall when the leaves start to change and the nights cool off, she'll be at the front door. I let her in and there she'll stay all winter, sleeping on my lap or on my bed, not moving except to eat, drink or use the litter box, nudging me frequently to be pet and cuddled. Come spring it's off again, avoiding me like the plague.
Has anyone else ever known a cat like this?
