I'm sorry...someone said Santee and I thought it was you....
I haven't used them, but there is an exotics specialist in Mission Valley that many other vets refer to.

Also, any vet should be able to do a fecal exam for parasites. That's not unlikely.
Have you contacted the store that sold her to you? They should be able to point you to a vet that can be helpful.
If you feel that your room is warm and cozy, then it's probably okay for her.
