Thanks Husky Mom once again for responding. I have thought deeply about taking them to the vet, and I have enough money, too. The reason I haven't yet is 1. they are pretty unsocial and I'm worried about them getting traumatized by a vet and 2. although I have the cash (it's the money I'm using to save up for a bird) I would like to avoid the vet bills because at my vet taking rats in is very expensive. I don't know if she shakes because she's ticklish or if it's another problem. I have also thought about it and I will probably wait until the rats pass before I get a bird, but I guess I'll make the ultimate decision after I get to talk to the very experienced bird breeder of 30 years and pet shop owner down the street from me.
