I love having rats! I have had bunnies, gerbils and mice in the past. This isn't a problem with me but I just wanted to tell you that you spelled "gerbels" wrong. It's actually "gerbils" fun survey!
We have a hamster, 10 rats (8 are babies born on 9/7/07), and 5 bunnies (3 are newborns born this morning. 2 of the babies were killed by our cats and the 3 we have we found scattered by the stairs... The're lucky they survived.)
