For this reason I decided to breed my own rats. I cannot depend on a clean source of rats from ANY pet shop. On rare occasions now I need a handful of medium rats for a few big girls. I hope to be fully self sufficient on rats by spring since feeding is slowing down now during the bp breeding season. I have 36 female breeder rats and will add at least 20 more by spring.
That's a common problem. Fortunately my rat source only has rats, mice, and ASF's on the premises - no reptiles!
