The necklace is just ruddy well barmy for the cat to wear or for a human to wear - it's creepy. But I think the felt things are not too bad. It's not as though a cat's been skinned which is outrageous but if it's just fur collected from your own cats thta you know is clean and you want to make soemthing then I think it could be a nice way to remember your cat when it's gone to the Bridge.
