Cat likes it, but he’s gained weight

We switched to this from the Hills since it was constantly out of stock and my car had previously likes the non-prescription ProPlan.. Well he’s been on a combined metabolic/cd diet for a while now but since starting this food he’s gained two pounds!! He likes the taste of the food, but we give him the lower amount stated on the bag for his recommended weight/weight loss and I’m so upset that it’s done the opposite of what it’s supposed to do. I’ll be on the lookout for the Hills brand again so he hopefully does better.

Purina OM weight management food

I was pleased with the way my cat transitioned from her regular food to OM. The bag of food had clear instructions on how to manage the transition. She's experienced no gastro-intestinal issues in the process.

It’s working

Since I’ve started using this my cat has lost some weight so it’s doing its job. The price is ridiculous and would prefer it to be more reasonable.

Cats like the food

Both of my cats are overweight. My vet suggested this food. I was shocked that both cats like it! One cat has lost weight but the other one has not, most likey because he also eats wet food as well and managing portions between two cats is difficult. I also like the fact that it protects them against urinary issues. Its pricey but I will continue to use it as long as they like eating it.

Very fresh food

My Vet has put Metoo on a diet, as she thinks she is still the "runt" and eats everything in site. She should weigh 10 lbs but weighs 15lb. I am saving money by using the auto ship for the prescription food over the cost of the Vet's pharmacy. It was well packed and has a long expiration date away. I am extra pleased with Chewy

Good results!

My cat weighed about 20 lbs and her long fur had become matted. The vet recommended this dry food and she has not only lost weight (it took a while) but her fur is now silky smooth. It made a difference!
