Looking For The Best Cat Food For Urinary Crystals?

Here’s a look at our favorites, including our top pick – Purina ONE Urinary Tract Health Formula Dry Cat Food.

#1 Best Cat Food For Urinary Crystals


Cats are just as prone to urinary tract problems as humans are. Bladder stones and urinary crystals are usually a problem when there is too much protein, phosphorus, calcium, or magnesium in the system. When these can’t dissolve properly in urine, crystals and stones begin to form.

The bad news is that these can be incredibly painful and if left untreated they can lead to dangerous bacterial infections. The good news is that urinary crystals and bladder stones are both easily treatable and preventable. One last thing to mention, we have a separate guide for sensitive stomach and vomiting available. Also another buyer’s guide for older cats, if you have a senior kitty at home.


What to look for in cat food for urinary crystals

Here are a few things to look for when you’re picking the best cat food for urinary crystals:

  • Low Magnesium – the dominant theory on how to treat urinary crystals and bladder stones is to reduce magnesium intake. While protein, phosphorus, and calcium can also lead to stones and crystals, magnesium tends to be the most common culprit. As such, a good cat food for urinary tract health should have low magnesium.
  • pH Balance – most veterinarians agree that the pH balance of your cat’s urine should be between 6.0 – 6.5. If you take your cat in to see the vet for urinary tract issues, they’ll probably test for that. A good cat food for urinary crystals should contain ingredients that lower/balance the pH level in their urine.
  • Water Consumption – generally speaking, drinking more water helps to flush out existing crystals and stones and to wash out the building blocks of crystals and stones before they have time to form. That said, getting your cat to drink more water is a lot easier than it sounds. Some cat foods will contain ingredients that cause your cat to drink more water and increases their urine volume. Taurine is probably the most common ingredient for this purpose (the same energy-producing agent you’ll see in most energy drinks).

You probably noticed a trend with our discussion today—4 of the 5 best cat food products for urinary crystals are made by Purina. The company has invested a bunch of time and money into creating premium products with purposeful nutrition, working with veterinarians and nutritionists to engineer the best products, and it’s working.

It’s definitely a brand you can trust, whether you’re looking for something as simple as total nutrition or as specific as treating urinary crystals. All of their premium cat foods are recommended by veterinarians, and their product offering has multiple price points to meet your budget.

If you don’t already feed your cat wet food, I’d recommend adding some wet food to their diet to help with their digestive system. A well-balanced diet should include wet food and dry food, and if you’re able to purchase both products with tailored nutrition for urinary tract health, that’s even better.
