My cat Forrest was a little on the heavy side (18lbs to be exact) and the vet put him on this food. He LOVES this food. But the vet recommended that I slowly transition him into this new food and so far it is going good! He hasn't lost weight yet (its only been 3 days) but I have noticed he is eating less due to him being full (the food makes them full faster). I would recommend this food to anyone trying to get their cat to lose weight, I just have to remember that it will take 8 weeks to show results!

My vet prescribed this dry cat food (kibble) because my cat had loose stools -- I thought it odd, but I tried it, and it did help her stools become more solid (also adding 7 to 8 probiotic drops per 1/4 cup kibble serving helped as well).

Our veterinarian prescribed this food to help our senior cat loose weight. She absolutely loves it. She eagerly "asks" for breakfast and dinner, but is also eating a little less than her previous kibbles as she stays full longer between meals. We've already noticed a tiny weight loss and she is more active than she has been in months.

Not Compatible

This was meant for one of my cats, but neither of them seem to like it. They'd smell it and would walk away.
