I'm sorry, I know how hard that is, and it sucks. I hope in time you'll adopt another.
My cat, Wesker Butt is a deformity more than breed. They are called manx cats, and I'm told they happen when bigger wild cats like lynx and bobcats breed with house-cats. That is why he looks like a lynx with the big paws and the mane and the tiny nub of a tail. I was lucky to find out about these kittens when I did, so I have no way of telling you how to find one, other then heading to central Wisconsin.
