3 dogs, 3 cats, a horse (pregnant), a snake, 19 mice (10 breeders {possibly up to 4 pregnant} 9 babies). Yeah, I like animals, but I'm also a pre-vet student. I saved the life of one of my mice by sub-q injections that kept him hydrated when he was really sick. If your abyssinian is a cat, I'd say breed. They're one of the most popular cats today, easily in the top five (at least in US). It should be easy to find home for the kittens. If you're talking about a mouse, still breed, see if any of the babies come out really well. Then maybe think about developing the line.
