Giz was found to have a murmer, a gauge 3 and they did no testing except to monitor her blood pressure and do some blood work. She is on medication daily now and they have said nothing about any other tests, just bring her back for her annuals. I trust my vet since he know what frantic Meowmies we are and how quick I am to bring them in if I suspect ANYTHING is wrong. He could have ordered every test in the book and knows I would have paid for anything he said we needed.
