Task: Sentiment Analysis
Input (English): We have three cats, the youngest is about eleven years old, another is fifteen and our oldest is, well ancient.  That is what the vet told us ten years ago.  The youngest is a blob.  When he lays down, he looks like a footstool. The other two are arthritic and skinny.  Since we had such success with Canidae Platinum for senior dogs, I figured that we'd give it a try for our cats.  I'd had them on low ash Purina One Urinary tract formula for their entire lives and thankfully we had no UT problems.  Buster, the youngest, is still a blob after six months plus on Felidae for Senior and Overweight cats.  However, the other two are now much more active and we can tell that they are really "feeling better" since we changed their food to Felidae.  Even Prissy, the ancient one has started to play and tease the dogs by getting them to chase her, where before when she was on Purina One, all she wanted to do was to sleep.  I think that if you can get your cat on this fairly early in their weight problems, it'll be more effective.  However, the glucosamine will certainly help your older fur balls have a happier life.
Output (English): 5
