Dr. Bob came up with a course of action with Stripes and I'm transitioning him to the other food now.
My only complaint is that it took him a long time to get back to me. I know he's busy, but within next couple of days would be helpful. I had to wait a week the last time. And this was after ultrasound results. The radiologist had given me her original findings so I had some idea of what to expect, but I was worried about my cat anyway.
