Imagine the bill if the same was done at a human hospital.
Veterinarians work on the cheap. - You don't see vet's driving Ferraris with vanity plates that say ASSMAN, or some such.
And considering that veterinarians have the same required 8-years for their multi-species medical degree... And animal hospitals need machines from anesthetics to x-ray...
Seems we are simply at the reality that the money proposition will come out different when it's "Your money or Your Life" vs "Some money or your pet's well being."
