"Our older male cat, and my pal, Fu stopped eating and was clearly losing weight. An examination by Dr. Tanya indicated that there was some sort of solid in his stomach. It turned out he had a growth in his intestine that was mostly blocking the flow of nutrients. Tanya's surgery was risky but she removed the part with the growth and put him on a special diet. He's back to his normal weight and attitude and cuddled up next to me on my recliner as I type this. Five stars plus. -Craig Jungers :)"
