My cats loved my bed and my sofa. They also liked the windowsills which I put fluffy pillows on.
The other place they would nap is the linen closet, the bath tub in the summer months, and a nice big cardboard box.
One cat slept with me practically every night. The other one about half the night, or on the foot of my bed.
My windowsills aren’t very wide, but I do want a sunbeam for The Cat Presently Called April, and that means one of those comfy platforms.
I don’t have a lot of places for a cat to nap, but I will make as many as I can. Still, there is always my bed, and since I have a heated mattress pad, I’m sure the bed will be a favorite spot.
And I KNOW cats love boxes! The late, Great PV would kill for possession of cardboard box that held six half-gallon milk cartons!
And paper bags!
