Thanks once again for responding! This is such a decision right now. My rats have never had porphyrin around their eyes or nose and they've never wheezed or clicked. I really want a bird but I suppose I must do what's best for the rats and the bird. I guess I could possibly convince my parents to let me house a bird somewhere else in the house. So, for sure, I should not house a bird and 2 rats in the same room?
