My lady cat is built like a little bear cub. Being a lady she is fascinated by bags. Seeing her trying to squeeze her curvaceous frame into a tiny handbag is pretty entertaining.
She sleeps on a box of junk in my bedroom - it can't be at all comfortable but she likes it.
Her brother prefers his comfort and sleeps on his duvet.
My fab princess of a cat sleeps on a hessian shopping bag draped over an old cardboard boot box on the hall floor in preference to her padded bed, sheepskin radiator hammock and my lap - I just love her to bits!
