i just purchased some feeder rats from a breeder for the first time.When we went into his house he had a his rats in breeder cages that had not been cleaned for a couple of weeks he admitted.they were also with out water and his house did not have AC so it was at least 100 deg in there.obviously he smelled horrid!!! I also noticed that he was feeding a cheap brand dog food.So with all that my question is can it be possible that these rats are unhealthy to feed?Thanks for your ideas
