Well, I have, it was here, and now I have come back. I Still think I'll have to come back here again soon.
I make harnesses for pets (dogs, mostly, and a large pot-bellied pig, though the design is very adaptable; I believe we could suit anything from a Hammerhead Shark to a Komodo Dragon). Though cats are pets, I have to say cats really don't care to be harnessed. I can't recommend this.
