Skinny Kitty

I am really worried about my cat. He has been sick since Dec. 8th. Well actually, before that...that is the date I brought him to the vet to begin this ordeal. I noticed he looked skinny and when I brought him to the vet he was 10lbs 8oz from his original 15lbs! They ran the whole blood work on him and found out that his pancreatis enzymes were sky high. So he had pancreatitis and a very mild case of kidney failure but nothing to worry about on that front as it is normal as his age (per vet...I wouldn't know). So my vet suggested I see an internal medicine specialist to do a ultrasound for the kitty to check for tumors and the like. I promptly scheduled the service as soon as I could.
