Heather, you might try giving him some Nutra-cal. It did wonders for Tiger. Although she is less than 1 year old , she had developed dietary problems early in life. When I took her in for spaying the vet read the write-up that was submitterd with her. She recommended Nutra-cal to help her recover from being weak when Tiger hasn't eaten in a few hours. Now, practically every morning she is running through the house and playing with all sorts of things that she finds on the floor, even playing with the kittens.
