Oh man, so adorable! I used to have a rat, Ratigan, but he was nasty because he was not properly cared for by his previous owners. I've been wanting to get another one, but I am worried about how my ferrets would be with a rat...
They live for about 3 years I believe. They are wonderful pets, but they do need more room and more things to play with then a hamster. Rat's are very smart.
