Pepper loves it!

My cat has FIC and this food helped her improve dramatically. She's only 4yrs, and in addition to losing weight with this food regimen, she stopped soiling parts of the home where she wasn't supposed to. She's shown drastic improvement!

Great For my Kitty but SO HARD TO FIND

It's so hard find. Even my vet has trouble getting it and they prescribed it.

Great food!

I got this for my two cats. I felt like this food was perfect for them and love the added "calm" benefit.

Our cat loves it!

We've been feeding this to our cat for a few months and he loves it. It was prescribed by his vet and his health has been doing better. This is a great brand and we're very happy with it.

Morsels in gravy

I have been feeding this to my spirited cat Milo for the past two years. Thankfully he has not had any more urinary accidents outside of his litterbox,and it seems to have helped him be less aggressive.

The only canned food he will eat

After our beloved cat had his second urinary blockage we began the hunt to find a new special diet that he would eat! It took a month and A LOT of frustration but this food finally did the trick! He ate it! I cried! Six months later both of our cats are on the SO + Calm and we have had no issues! We buy this canned and the dry formula and they take both without complaint. THANK YOU for making a palatable formula that our stubborn baby will eat!

Easy switch

My cat is a picky eater but needed a diet specific for urinary issues. She is also a bit of a nervous cat which just adds to her urinary issues so this food was a great choice. She took right to it and I can truly tell the difference in her.

My cat loves this!

My cats eat both wet and dry Calm. Only one cat needs the Urinary wet and he loves it. I'm not sure how well the calm works since he is an oriental short hair mix and is very active and extremely vocal but I'm so happy to find a urinary wet food he will consistently eat.
