I used to breed Abyssinian cats. The absolutely most gorgeous cat I ever produced was a female. She started spraying at about 6 months. I got her spayed - which meant, alas, no kittens from her :( She kept spraying. She became an outside cat, even though my contracts on kittens I sold said specifically that the cats don't EVER go outside or if I find out I'll take them back, no refund, sign on the dotted line.
Rascal was a beautifully wild-looking thing to watch as she'd bound through the neighborhood when I called her :)
Most of my cats have just been 'cats', but I think Abbies are a wonderful breed.
