okay, I have a pet rat, Oreo. He started out as a feeder, but became a keeper. he is under 6 months old and adult size already. Two weeks ago, I purchased two weaned rats as feeders and they were not eaten :/. So now, my question is, can I put the two weaned rats in with Oreo or will he harm them? We do interact with Oreo on a daily basis, but I do know that he needs a rat buddy for optimal health and well being. any advice is greatly appreciated and thanx in advance.
