My cat loves it!

My cat gets stressed easily and developed bladder issues. This food helps ease the urinary problems.
22 Oct 2019

They both loved it at first. But then,

This was prescribed by my vet and at first both my cats loved the newness of the food. But after a few months they've become finicky and they don't love it as much anymore. I'm subbing in another brand and will wait until they like it again.

Urinary diet

My cat has been on this diet for about 5 years now. He loves the morsels in gravy. Even my cat who does not need to eat this food gobbles up the food. While he doesn’t really like the dry food he does eat it (he has no choice) but doesn’t hesitate to sneak a mouthful from the other cats food occasionally.

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!
