I was very skeptical when vet put her on an OM diet. She turned her nose up at other prescription foods given to her before. This time she started eating as soon as I gave it to her. She likes this and the wet OM canned food. So far she has shed about 3 pounds and is happy and satisfied. She is like a new cat with more energy. She is a feral rescue who had issues with regular cat food. She had problems with her gut and put on lots of weight. Her issues seem to have resolved and she is well on her way to a more normal healthier weight.

Our cats were on a Hills RX Metabolism food to control weight for quite a while but the results were disappointing. Our vet recommended the Purina OM as an alternate. We have slowly converfed them over to the OM. They both like the food, but it is too early to tell about the weight control effectiveness at this point.

Glad to have something available for overweight diabetic cat!

My cat seems to like it. What I'm not so crazy about is that it only comes in 16 lb bag and I only have one cat on it.

Seems OK for diet food

What I think about the food is irrelevant, but our cat is eating it, albeit less enthusiastically than his previous food. I suppose that’s to be expected with diet

What I think about the food is irrelevant, but our cat is eating it, albeit less enthusiastically than his previous food. I suppose that’s to be expected with diet food. The verdict will be given if we see a little weight loss.

No resealable bag?

My cat seems to like the food, but the bag is not resealable. There’s no zipper or Velcro closure like you’d find in basically everything else in your house. So, once you open the bag, you have to store it in something else to keep it from spoiling. Disappointing.

I bought this for my newly diagnosed diabetic cat and my other overweight cat to help them both lose weight. None of my cats will eat this food. They sniff it and walk away. Very disappointing because this food cost a lot of money.

Prescribed for a diabetic cat. Did not expect him to even try it, but after one sniff, he started munching away. This dry food must have an appealing smell and taste, so recommend for a cat that needs to reduce carbohydrate intake.
