Hi, although i don't post much i absolutely love reading the forums and now that i'm out of school i promise i'll post more! Anyways, i have two rats named shirley and charlotte and they are about 7 1/2 months old. They are not the nicest rats and they bite alot but i'm working on taming them. They've always had problems with mycoplasma, but i haven't ever taken them to the vet because it's an off and on kinda thing. But lately, when i hold Shirley, she'll start shaking terribly. During these tremors, she'll sometimes sneeze, but usually she'll just eventually stop. Can anybody explain this? Also, in about 2 months i will be getting a budgie. I was wondering if it is safe to house 2 ratties and a bird in the same room? Can they give eachother diseases? Any input would be great!
