Questions & Answers

20 Customer Questions

Is this good for crystals ? Or just uti ?
Answer by ChewyOct 06, 2017
This formula helps maintain urinary tract health by reducing urinary pH and providing low magnesium. We recommend consulting with your veterinarian if you suspect your cat has crystals or a urinary tract infection.

Can this food be fed to other adult cats in the household which do not have urinary tract issues?
Answer by ChewyAug 15, 2018
With this food being a complete and balanced diet, it would be suitable for cats that do not have urinary issues. Animal feeding tests using Association of American Feed Control Officials (AAFCO) procedures substantiate that Purina ONE Urinary Tract Health Formula provides complete and balanced nutrition for maintenance of adult cats.

Is this formula recommend for cats older than 7 years?
Answer by ChewyNov 13, 2018
This food is formulated for adult cats. In most cases, cats can be considered senior when they are between 7 and 10 years old.

Will feeding this long term aid in preventing kidney dysfunction later on?
Answer by ChewyJun 07, 2021

Formula changed?

I started buying this Purina urinary care formula last year when one of my 10 cats started showing signs of having crystals. Things seemed fine until this last order. I don’t know what Purina might’ve changed, but the last order (two 16lb bags) was definitely different. Within days of opening the first bag, half of my cats started throwing up so regularly, I could barely keep up with cleaning up after them, especially with a couple of them suddenly having yellow-colored diarrhea and needing rear-end cleaning daily. At first, I thought perhaps it was just that the first bag had gone bad, but the illness continued through the second bag. Now I’m afraid to feed it to them at all, so I’m switching to the Iams equivalent for my next order and crossing my fingers their health improves.

Jury is Still Out

I ordered this because the urinary track and immune health dry cat fud that I normally order was out of stock ... but not before it was already included in my order but I bought this for when it runs out ... so we're still using the other fud so I don't know how this will go over with the kitties yet. It is the only other non-prescription-requiring dry cat fud that I can find for urinary tract health and that is a winner as far as I am concerned. Cat owners should not need prescriptions for something that is so common for all male cats, that all cat fud really should be able to be made that way. Especially since I would have to take off several days from work in order to get an already traumatized and abuse surviving rescued cat to a vet just to be able to buy food for him. I thank Purina and 9-Lives for understanding this. And I thank Chewy for carrying it! It does, however, cost 3x as much as the other brand, which is why I prefer the other brand to this one. Because I rescue cats.

Read reviews!

Purchased this in an effort to help my 9 year old guy. My first thought is why is it yellow? Then I looked at reviews and ingredients to see that corn is the first listed. I usually buy purina one and didn’t think this product would be different, well , my cats don’t like it all all, even my lab who likes to sneak the cat food, passed on it. Lesson learned. Read reviews!

Our cat nearly died from a urinary blockage a few years ago. He needs special food to stay alive. This is the only urinary tract cat food he will eat. I have had a hard time finding this locally. Thank goodness for Chewey and their quick delivery service. It quite literally saved my cat's life.

Cost Affective

Our cat has urinary track issues and has to eat this type of food to keep from getting crystals. It cost quite a bit less than most of the others and he eats it better than the other brands.

No one wants to eat!

The food that that not even a 22 pound cat who loves everything. This food is now going to sit in my closet, I will donate it and hope very starved cats will eat it. Also the 4 year old cat with the urinary problem just passed away in my arms. So this food sucks!!

I was very disappointed that my 3 cats did not like this variety of Purina One. They usually prefer Purina products. Now they walk away from the Purina One, leaving it in their dish.

Save your money

I have 2 inside cats and 4 outside that feed and care for. Do not buy cheap cat food that can lead to get bills. Not one of my cats will eat this . I left it out over night and the RACCOONS must have eaten, Blue jays love cat food and they did even touch it.

Something has changed

I've been feeding this food to my cats for years and have had no issue, now they seem to not want to eat it and have lost weight, my one girl has lost a significant amount of weight and her coat looks terrible!! She will be going to the vet for a full work up. I went and got a bag of different food and they swarmed the bag and ate every bit of food I put out of the new food. I've also made sure to keep an extra 16lb bag at all times because of the supply chain issues, so I have all this food they won't eat now!!!

Expired rancid food

I received my first autoship of this cat food. When I opened it, there was a bad smell and the food did not look right. Under further investigation there was huge clumps of food that barely resembled cat food all throughout the bag. Something was definitely wrong with this food. I found the expiration date and it was expired 1 1/2 years ago. December of 2021 clearly marked on the bag. I contacted chewy, where I was told I was issued a refund and someone else would be contacting me to follow up and make this right. I never received confirmation of a refund for this food, or a follow up from anyone at Chewy. All I was was sent the opportunity to review my Chewy items. I am posting this so others will be aware and hopefully this will not happen to them. Very disappointing with chewy and I will be cancelling my autoship future orders and no longer order pet food from them.
