Yes, they can make good pets. However, since they are intended as food, and not expected to live long, not much thought is given to how healthy they are. If you take on a feeder, be prepared for the fact that he or she MAY not be the most healthy specimen, and may result in higher vet's bills. Also be careful when taking on female feeder rats, as they are often lumped in with the males, and could be pregnant. If you can take all that into consideration, and be ready to deal with that if needed, then yes, they can make good pets.
