Thank you all for your responses. I took Max to the vet yesterday, after fighting IBS and Kidney problems for 2 years, we decided it was time to let him go. He was under 5 lbs, but still eating really well, and drinking plenty, but my vet said he was dehydrated, and he was not getting all or any nutrients from food. We had him on Viokase and prednisolone for quite awhile, but I couldn't put him through anymore. Out of my six cats, I'm down to two now, a 16year old and a 12year old. It's been tought the last 2 years.
