Thanks everyone. Should I wait a few days before I get a new friend for my other rattie? I would really like another hairless, but am thinking that I shouldn't get one, because their health is really more fragile than rats with hair. I'm still not sure why Sue died. She died in her sleep. I'm not sure how old she was. Maude, the other rat, seems kinda lost w/out her. I held her last night for a long time and she cleaned my hand, which she has never done. I guess she misses Sue. But, I'm just gonna remember the time I had with Sue, and how sweet and gentle she was. I don't think she was ever really healthy, cause she wasn't very active, and she slept alot. I just hope it wasn't something contagious. I disinfected the cage, waterbottle, and bowls, and threw out all the old toys. I'm going to keep my eye on Maude, and at the first sign of illness, get her to the vet. I guess I just thought that since Sue was older, she was lazier. Anyways, maybe I'll go get Maude a new friend today.
