My 12 year old budgie has a tumor on her uropygial/preen gland. She is on antibiotics and an anti-inflammatory, and then at re-eval the vet will decide if it is operable. I guess I just never thought of a tiny little bird being able to hold up to an operation, but I was surprised that this was a viable option. The vet seemed pretty confident about its safety and said she has successfully operated on zebra finches and goldfish (!?). The vet didn't really seem to "hear" my concerns. It didn't seem to make any sense to her to even be worried about it. I don't know if she has just done so many that she is very comfortable with avian surgeries, and I am just totally ignorant of how common and low-risk such surgeries are... Has anyone had positive (or not so positive) experiences with the outcomes of birds, especially small/elderly birds, that have been operated on? I want to do everything I can for Tegan, but I do not want to do anything that will have the actual effect of lowering her quality of life.
