It was just a visit. There were no tests done on Humphrey, other than the vet feeling his stomach for problems and checking his ears. This is why I was so shocked that she would even mention surgery. She even told me how much it would cost! I'm not concerned about cost, I just want my cat to be healthy. It was so strange to me.
He seems to be feeling a lot better today. I'm starting to think he just has a sensitive stomach and can only eat certain foods. I want to get his health to 100% though. I'm still keeping a close eye on him.
