eeww, you have a rodent as a pet! :-) 
Speaking of this, I went to the vet today to pick up Reesa (she got fixed today...) and there was a lady there who had something sitting on her shoulder. At first, I thought it was a ferret, but I was wrong... It was the biggest rat that I have ever seen!!! In it's defence though, it was actually quite a pretty rat.... for a rat....
