In a previous submission, there was a lot of interest in my pet rats, so here's their introduction! The two oldest, Nibbler and Fry, we acquired about a year and a half ago, and the two youngest, bender and zoidberg, we got about four months ago. They're all full grown just about. Nibbler and Bender are both pretty fat... but Bender is just a bit bigger than Nibbler. Zoidberg is VERY skittish, and we assume this is because he gets very scared of things he can't see well, or doesn't know what they are. They're all very friendly, however, and will come to the open cage door to get treats and scratches, and to be let out to play.
