Thunky Lou has put on a pound or two. He is 14 pounds now. Theresa did some research and found out that cats do not handle carbs very well. Lots of cat food is loaded with carbs, and the soup Theresa makes had paste, rice, and lentils. Well no more, he on a mostly protein diet now. Lots of chicken, tuna, and salmon. He has done a bit of time on the tread mill as well. We get him into shape here soon.
