I have a female American toad that hasn't eaten in pretty long time and her eyes are constatnly constricted. I'm not sure what it could be. Vitamin issues? Stress? Cold? I have the warmest room in my house and have a small heat mat on the tank. She is housed with another americna toad and two gray tree frogs which will get their own enclosure before my winter break ends. I'd really like to take them to the vet because of hwo difficult it is to find one. Plus my aunt who works at a veterinary clinic near chicago said the only one she knows of here is pretty expensive. Any ideas?
