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!

Purina OM diet catfood

Our very over weight cat loves the dry food not the wet food. We did not know which one she would like so we got both. Chewy was very good at crediting our account one the wet food since it was opened and cans were used.

Cat approved

I was nervous switching my cat's food over to OM because she's not a great eater and I didn't want to rock the boat, but she absolutely loves the new food!

My cats love this food

I have one overweight cat and another who is a finicky eater, who decided she no longer liked the original food we were feeding her. Switched to this food at the recommendation of my vet. Both cats switched easily and really seem to like this dry food.

Problem with last bag purchased.

I used this product for a long time without a problem but the last bag I received caused my cat to throw up.
