I bought this for my black cat Merlin. I have to say it is cute as ever on him. It has a velcro closure so would fit any size adult cat. The "fur" needed a little combing with a large tooth comb to straighten it out when it first arrived.
I plan on Merlin wearing this for Halloween and then for other occasions. He, like most cats, does not necessarily like it being on but after a few tries he tolerates it.
