Task: Sentiment Analysis
Input (English): We have five cats - one an elderly cat of 15 years, the other four in the 9-11 year range.  The oldest cat was diagnosed a couple of months ago with the beginning stages of chronic kidney disease.  His numbers didn't warrant being on prescription food yet, but we needed to start paying attention to things like protein and phosphorus levels in his food.  Because we have five cats, and some of them are nibblers eating four or five nuggets at a time, we decided to switch them all to an acceptable food for the oldest, so we picked the active longevity because it specifically mentioned kidney support and calories appropriate for less active older cats.  Since we made the switch 6 weeks ago, all of the cats have gained weight.  This was fine for the little old guy as he was a bit underweight; not good for the rest of them.  Our other male went from a slightly chunky 18.5 lbs to an obese 21.25 lbs - almost three pounds in 6 weeks!  The 3 females gained between 1.5 to 2 pounds each.  We noticed them making a lot more visits to the food bowl, like they couldn't seem to get full.  We also saw a lessening of coat quality - lots of shedding even though they are brushed regularly (including with a furminator) and one developed bad dandruff.  The stools developed a really bad odor, although I do have to say nobody developed diarrhea which I am grateful for.  Most worrisome was that the lab results on the old guy came back with some of the kidney values of concern having worsened.  I am very disgusted with Science Diet - they are actively fooling the public with the nutritional claims on the bags. One of the sites I researched on for chronic renal failure has charts detailing the nutritional breakdown of most of the various foods available.  If you compare the various Science diet formulae that have different health claims on them - the nutritional values for the components listed are all within a tenth of a point or two.  Basically from the nutritional analysis it appears that they are  the same base formula with maybe a slight difference in a vitamin or additive.  With other brands, such as innova or royal canin, there appears to be an actual difference between the different formulae.  Now to deal with the weight gain, as well as the other problems we noted, we are switching foods again.  This time we are trying royal canin indoor mature.  Wish us luck.
