What is the purpose of you breeding the rats anyway? What if you cannot find homes for ALL of those babies? Are you going to keep them, or sell them as feeders, or return them to the pet store, where they will probably just be sold as feeders?

You said that the male was an inbred mess and that would in turn make the babies unhealthy... I just dont understand the reasoning.

The females may be healthy now, but if you keep breeding them over and over again without a break, then they will not be healthy.

My suggestions is to get 2 males this time from the pet store, so he will have a buddy, and keep them away from the females.
