Here's a description of the Caracal cat. IMO its not a "small" cat - they are quite a bit larger then even a large domestic cat like a Maine Coon or a Ragdoll which can get 18 lbs. This cat is at least twice that size. And you are breeding it to an 8 lb little Aby????? Which means a small Caracal is almost 4 times the size of the Aby!
