Congratulations on dumbfounding the vet! Two years ago we were told that ours had a heart murmer and wasn't expected to live long. She's now turned into a juvenile delinquent! What do they know?
Finding a good vet is the same as finding a good doctor.
When my current baby was bitten by a snake (which I didn't know at the time)
The first vet I saw did a blood test for snake bite, but it came back negative so she moved on to guessing about other things. In the mean time our cat's face was paralysed and she was struggling to breathe, then, thankfully, the senior vet arrived and said that he didn't care what the blood test said, he had treated hundreds of cats for snake bite and he believed that is what it was.
He saved her life.
The first vet had missed diagnosed my previous cats illness, which ended up costing him his life. (you could say that I don't like her very much.)
