That's great news for you to have what seems like a relatively positive prognosis. Like you, my primary vet is older and approaches most situations holistically and I absolutely adore him; I have a secondary vet "clinic" who has all the modern equipment, but who unfortunately falls short in the personal care dept.
My thoughts are with you and Kitty. It sounds like you're on the right track. I'll look forward to hearing how she's doing over the coming months.
