When Mike was little, he had two gerbils, Brownie and Blackie (five points if you can guess what colors they were!) as well as his bunny, Nibbles (a female black netherland dwarf bunny). We don't have any Gerbils now, but I'd like to try keeping them sometime in the future, since I've never kept them. I've heard that they are not nocturnal like hamsters, so that's another good reason to try them.
