I believe the dumbo rumor started partly because the rats tend to have a more "innocent look" to them and partly because they were originally bred by responsible fancy breeders who were trying to breed friendly animals. However, the standard-eared rats from responsible breeders are exactly as friendly--no more and no less, and dumbo rats from pet store/feeder lines are just as nervous and poorly socialized as their standard-eared counterparts. The appearence of a rat is just that--appearence. Their family history and their raising is what makes the difference. The same goes for mice, hamsters, and gerbils. Don't get fooled by pet store labels/prices. Those "feeder rats" probably came from the same litters as the "fancy rats", "dumbo rats", "Rex rats", etc., and have just as good a chance of being great (or bad) pets. The "breed" that makes the best pet is any rat from a responsible breeder. So, let's knock off the "rodent racism"...
