The goddess Freya was said to have mitts made from cat fur, so probably that, at least! The pelts are a good size for hats and mittens.

Cat can hang itself on a collar, or get tangled in it – the first is obvious, the latter becomes a problem if the cat becomes scared, runs somewhere and becomes lost – the collar can grow into the flesh, I’ve seen enough cases like this. If somebody is hurting your cat, best keep him indoors, you don’t know what this person is going to do next time. The cat will demand to go out, but after some time he will become accustomed to staying indoors, especially with a lot of stimulation with play, hiding treats in sniffing mats and so on.
