Hard to Get

Why is this food so hard to keep in stock? Our senior kitty is very happy with it, and needs the multi-function support. Can you please make this more consistently?!

Agree this product is INTENTIONALLY undersupplied

I agree with a previous reviewer that this unique product is intentionally undersupplied, often unavailable, and RoyalCanin is able to price gouge. I've contacted my Senators and Representative about my concerns.

Great food, but difficult when out of stock

It's great to have a renal and hydrolyzed diet available for my cat that he actually likes. Because of his food allergies he's unable to eat regular, prescription renal food and having an option that addresses both has been fantastic. And having him like it is even better! However, my vet and my vet's supplier have been out of stock for awhile now which has left me scrambling trying to figure out what to do. With a product so niche, I wish priority would be given to making sure it stays in stock.

Great but always out of stock

This is a great product that has helped my 18.5 year male cat but it's so hard to find!!

One of a kind. IMPOSSIBLE to find.

Saved my cats life. Issue is finding it. NOWHERE can you find it online in the US. I’ve only been able to find going store to store. Price changes drastically each time. However, I think it’s kept my cat alive so I’ll go broke searching for this stuff..

Can't find it anywhere

Only reason I give it a 3 is it is ridiculously hard to find, can't even get it through the Royal Canin shop.

Awesome for my kitty with IBD

We have a kitty who has had diarrhea for years. We tried different sensitive stomach diets, probiotics, and daily antibiotics. The only thing that worked was daily antibiotics, which were a nightmare to administer and made it hard to go on vacation. Then he developed kidney issues and lost a bunch of weight, so our vet had a consult with Royal Canin about what might help given his various issues. They recommended this food. Within a day he was having the most normal poops he's ever had. He has gained his weight back and loves eating this food. I don't exaggerate when I say I got teary eyed when I realized we had a solution to health issues that have been making all of us miserable for years. My only beef is that it's worrisome when it's out of stock or on backorder, because there's no alternative for cats who eat this food. I hope the company is prioritizing production for special formulations like this.

Grateful for this diet

First, thank you for making this diet. Not sure where we would be without it. My cat has been on it for two years and it’s probably helped save her life. However, the consistency was way off on this last bag. There are a lot of very large pieces that look like multiple kibbles were extruded together and not separated. After two years of consistent kibbles I am wondering what’s up? Cats are pretty picky about shape and cats with renal and IBD even more so. This food isn’t cheap so if 10% of the kibbles are deformed like this and rejected by the cat it adds up. Still giving it 5 stars because it’s keeping her alive and she eats it well most of the time.

Different Formula Between Batches?

My cat has been on this for years and it has been fine. Last two weeks she refused to eat it. After trying a number of different things to get her to eat, I tried opening another bag for her and the two bags are completely different in color and shape. This new bag is a lighter shade of orange/yellow and smaller kibble. As soon as she got into this new bag she began eating again. I'm not sure what is going on with the consistency of the formula, but since this is the only food of its kind it is concerning if it's not always the same. Overall it has help her immensely, but it's expensive and difficult to find.

Cat Hates New Formula

I wholeheartedly agree with Csmith. My cat used to love this cat food and it took forever for us to find something she would eat. We would buy several bags at a time since it was so hard to find. Now that we opened a bag of the reformulated food she HATES it and doesn’t want to eat. Bring back the old formula.
