Since we are on tangents here, my downstairs neighbour owns a half-serval. It was illegally imported and abandoned: she takes care of it, together with another dozen of cats. When she has a litter, she needs to keep the serval away from the litter or it will kill the kittens.
What's the other half?
Probably regular domestic cat. They can and do breed.
She thinks that is indeed the case, but she isn't sure. She just knows it isn't a full serval.
she should breed it with a female house cat and make
a ¼ serval
Since we're going on tangents here, I've taught an animal behavior class.
