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.

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,

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.

Pricey but kitty did like it

I didn’t notice weight loss so I couldn’t justify the price for the product but that said, it was a good product and kitty did seem to enjoy.

A little pricey for a 16lb bag, but that said, it's good quality food, and my cat still seems to enjoy it. More than a couple of times he "accidentally" knocked over his auto-feeder and nearly had a buffet for his taking. Nearly. :)

Need it on time, don’t use Chewy

I spend a fortune at Chewy. Looking for new solution because Chewy can’t deliver on time and doesn’t care. my big spend is no big deal to them.
