Rachel - You are not helping your cat or yourself - no vet cares more about money than an animal! IT IS THE CAT that is IMPORTANT. Veterinarians have to follow the rules! IF you wish to have home care (a mobile practice) then that veterinarian has to take the responsibility to take medical care of your cat. It's that simple. Anger is understandable as you don't understand completely- but I am sure you were raised to be nice to all people.
I have to be checked monthly with my MD for my meds - Veterinarians have to do the same thing at intervals to make sure nothing has changed - That's what they went to school for - to see the little things that owners overlook. Happy birthday to your cat! Who is living because of Dr. Karnia's excellent care.
