I acquired a 27 year old Congo African Grey from the back of a vets office. She had been abandoned by her owner and stayed there for like 5 years. I was told she had severe arthritis and in turn mutilates her right foot. She is on Metacam and Gabapentin for many years. She has been kept in a collar constantly to keep her from her foot. I took her to a different avian vet and was told the xrays showed no calcification in her joints but possibly a large blockage in the main artery on top of heart. That Dr stated she could be experiencing neuropathy due to low blood pressure. Nothing was done or medication changes there and I will be taking her to an avian hospital on Wednesday. .... Her foot has now began to change color and the mutilation is at a peak. She has become very aggressive the past couple days and torn a chunk out of her thigh. I am contemplating amputation if I can't find relief. I have pics I can send, but didn't want to gross anyone out. Thanks for any advice and help.
