In the 35+ years that I've owned both dogs and cats, and of all the vets I've visited in 4 different states, Montana is without a doubt the absolutely, unquestionably WORST veterinarian I've ever had the displeasure to come contact with.
My 14 year old cat developed hot spots all over his head and paws. Montana said that the cat needed to be on antidepressant medication. I asked him about this medication, and he actually yelled at me, telling me he didn't know anything about the (basic) question I asked him. He is the rudest, and least informed vet who had the worst bedside manner of any vet I've ever known.
He also handled my very sweet kitty far too roughly.
I took my cat to another vet the following week, who referred me to a veterinary allergist, who helped cat immensely. The allergist could not believe that Montana recommended an antidepressant medication for my cat without doing ANY kind of testing for what was causing the hot spots.
Please do not take any animal that you love to this completely inept veterinarian.
