They like towels too for bathing the dogs. Cats, not so much. I made my cat a sleeping bag when he had to stay over night. He likes to snuggle under quilts. Figured that gave him padding in the cage, smelled like home and he could snuggle in it. It was cold and raining when I picked him up so I just slid him inside and carried him to the car. Vet really liked it too.
