In A Hurry? Here Are Our Top Picks…



Best Overall Cat Food For Urinary Crystals

Purina Pro Plan Focus

Purina has our overall favorite cat food for urinary crystals. It helps your cat stay hydrated, provides a balanced diet, and sells at a reasonable price.

Wet cat food does a much better job at preventing urinary crystals than dry foods. The extra water in wet foods helps make sure that everything comes out alright for your kitty, so we love the fact that this is a wet food. In addition to helping your cat stay hydrated, this food helps maintain urinary tract health by reducing urinary pH and providing lower levels of magnesium.

This cat food also helps your kitty keep a strong immune system by providing vitamins, minerals, and an extra boost of taurine. That might not stop any existing urinary problems, but it helps to stave off future infections or bacteria in the urinary tract.

We do wish that there was a bit more protein in this food, but it’s not a huge deal. The reasonable price tag makes this a pretty solid overall buy.

Things We Like

  • Reasonable price
  • Helps your cat stay hydrated
  • Reduces urinary problems by giving your cat a lower urinary pH and lower magnesium
  • Supports a strong immune system

Things We Don’t

  • Could have a bit more protein compared to other wet foods

This is our favorite overall cat food for urinary crystals. It helps hydrate your cat to prevent crystal buildup, supports overall urinary health, and keeps your cat’s immune system strong. The reasonable price tag is pretty nice.

Best Cat Food For Urinary Crystals And Hairballs

Hill’s Science Diet Urinary & Hairball Control

Hill’s Science Diet has our favorite cat food if your cat is struggling with urinary and hairball related issues.

This is a dry food, so we don’t recommend it if your cat has extreme urinary problems. Dry foods just don’t “clean everything out” of the urinary tract like hydrated wet foods do. But if your cat has hairballs too, then this food might just do the trick.

It works on stopping urinary problems by providing your cat with optimum levels of magnesium. Too much magnesium can cause crystals and too little can cause some other organ problems, so Hill’s Science Diet tries to find the balance here.


This cat food works against hairballs by giving your kitty a healthy dose of fiber. Fiber helps with your digestion and is one of the key ingredients in cat food for hairballs. Another thing I like here is that Hill’s pumps their food full of Omegas 3s and Vitamin E to help your cat keep healthy skin and fur.

Buying just the dry food won’t help as much with urinary crystals as the wet food, but Hill’s offers a wet + dry option as well. The price here isn’t crazy awesome, but it’s not too bad.

Things We Like

  • Great for urinary crystals by providing optimum levels of magnesium
  • Helps with hairballs since it includes a bunch of fiber
  • Helps maintain strong fur and skin health

Things We Don’t

This is our favorite food if you have a cat who’s struggling with urinary problems and hairballs.

Best Cat Food For Urinary Crystals And Allergies

Purina One Urinary Tract Health

Purina has our favorite food if your cat struggles with urinary crystals and allergies. Their formula helps with urinary problems and limits several common allergens.

Purina’s urinary tract health food is wet, so it helps keep your kitty hydrated. That in itself is a big aid in fighting off urinary problems like crystals. Most cats prefer wet food, so this is also a pretty good choice for pickier eaters among us.

Purina’s formula helps fight urinary crystals by keeping your cat hydrated and by balancing his or her urinary pH. This prevents urinary crystals from forming and helps keep your kitty’s bladder health in tip top condition.

This food is also a good pick if your cat has some of the more common allergies. Purina doesn’t add any soy, potatoes, wheat, or corn to their food. This food won’t stop every allergy, but is a good choice to deal with some common ones.

This wet food has 31% protein. That’s not horrible, but we wish it was a little bit higher. It’s on the lower end for wet foods.

Things We Like

  • Reasonable price
  • Helps your cat end urinary crystals by lowering pH and keeping your cat hydrated
  • Good pick for cats who are allergic to soy, potatoes, wheat, or corn

Things We Don’t

  • Could have a bit more protein

This is our favorite food if your cat has urinary crystals and some of the more common food allergies to wheat, corn, soy, or potatoes.

Best Cat Food For Severe Urinary Crystals Or Problems

Hill’s Prescription Diet Urinary Care

Hill’s has our favorite cat food for severe urinary crystals and other problems. This is a prescription diet (though you don’t need a prescription to purchase on Amazon or Chewy). Since it’s prescription, you can be sure that this food will help the most severe of urinary problems.

Pro tip: It’s much less expensive on Chewy than on other online stores.

Check Price and Reviews on Chewy

Hill’s prescription diet’s main benefit is that it is vet grade food. When you’ve tried all other options and nothing has worked, we recommend giving this food a try.

This may not be a great food for a consistent diet for a couple of reasons:

First, it’s a bite pricey compared to other foods. It’s much less expensive on Chewy than other online stores, but you’re still looking at 3x or 4x the price per pound of other foods.

Second, this food is pretty high calorie. Even the most active cats may be in danger of weight gain.

We recommend trying this food if no other options have worked in getting rid of your cat’s urinary problems. If you notice that your cat is gaining weight, you could try mixing this food with another one of the options listed above.

We recommend talking with a vet if you think the problem is severe enough to warrant this diet. He or she can help you make sure that your cat gets the right portions, is maintaining a healthy balance of vitamins, and that the urinary problem is getting solved.

Things We Like

  • A great last resort option. This has a good chance of working when other options have failed
  • Much less expensive on Chewy than other online stores (check price here)

Things We Don’t

  • High fat makes it easy for your cat to gain weight
  • Pricey compared to other foods

This is our favorite pick if nothing else has worked out. We recommend trying this food when nothing else has worked and consulting with your vet if the problem is severe.

Best Budget Cat Food For Urinary Crystals

Purina Urinary Tract Health

Purina’s urinary tract health food is our favorite budget choice. Cats don’t always develop problems that we can afford to take care of. This food combines the most help possible with the best price overall.

Purina’s formula works against urinary crystals and other bladder problems by lowering urinary pH and providing a lower dose of magnesium. This food costs less per pound than other options, but provides a similar solution to the problem. Our only concern here is that this is a dry food, so it might not help as much with severe urinary problems. Wet foods help your cat to “wash out” and stay hydrated better than dry foods do.

Purina also works to keep your cat in good general health. They provide plenty of omega 6 fatty acids to help your cat’s fur and skin stay strong and healthy. The protein comes in at 31% and that’s not too bad, but it’s not as high as some other foods.

This is a quality food and will help your cat with non-severe urinary crystals. But you do get what you pay for: this food has a bit less vitamins, minerals, and proteins than other cat foods mentioned above. We recommend this food if you can’t afford the others on a consistent basis.

Things We Like

  • Helps stop urinary crystals by reducing urinary pH and magnesium
  • Your cat will keep a strong coat with omega 6 fatty acids
  • Great budget pick – most reasonable price per pound on this list

Things We Don’t

  • Not as many vitamins and minerals as other foods
  • Protein could be a bit higher, but it’s not too bad

This is our favorite budget pick if your cat has urinary crystals. It will help him or her get over their urinary problems while saving you some dollars.

What To Look For In Cat Food

Cat food that claims to be specially formulated to promote and support a healthy urinary tract is bound to contain few essential ingredients like vitamins that regulate healthy organ functions. Others are minerals that control pH levels of urine.

Other ingredients are those that prevent crystal or stone formations. Apart from the generic ingredients, you can keep an eye out for a few other additives that are great for your cat’s urinary tract health. A few of these are:

  • Staphysagris is a natural medicine used by vets for treating UTIs in felines. It works to ward off infections and calm the urinary tract. It also relieves the burning sensation caused by acidic urine.
  • Berberis Vulgaris or also commonly known as the “common barberry” is a shrub that produces berries. The extract from these berries helps induce a healthy immune system in both humans and felines. This raises the chances of fighting internal infections and restoring the health of the bladder and urinary tract.
  • Cantharis is an old homeopathic solution. It is primarily obtained from beetles found in Europe. It helps dissolve urinary crystals in felines.

You can look for supplements or look for recipes online on how to inculcate these ingredients to help relieve your cat of the medical distress. There are cat foods out there that may claim to have these or other organic ingredients as well.

While organic items sound great, they are not the absolute solution when conditions worsen. That’s where your vet comes in.

Moisture is a factor that contributes to your cat’s urinary health. Many people avoid canned cat food due to smell and preservation issues. It is still highly advisable to constantly keep wet cat food a part of your cat’s daily intake. Either mix it with dry cat food or serve in portions.

This keeps your cat hydrated. You need to make sure that your cat has plenty of water sources. One bowl of freshwater won’t do. It’s a good idea to get a small kitty fountain. Cats are more prone to drink from running water rather than from stagnant. That explains the lack of interest in their water bowl.

Change water daily as standing water or even overnight water can become a cluster of bacterial colonies, which isn’t healthy for your cat to drink. Also, avoid fish-flavored cat food since they are believed to be somehow a contributing factor to poor urinary tract health.

Wet cat food plays a vital role in keeping the hydration level up in your feline friends. Cats are not designed to consume much water. As natural carnivores, they obtain their water content directly from fresh meat, which contains 70% to 75% of moisture.

Urinary Problems in Cats

Urinary problems are among the most frequently occurring problems in cats. It is most likely observed in indoor cats. Causative agents can be identified through proper medical testing and diagnosis. Chances of bacterial infection are quite common that may lead to other lower or upper urinary tract problems.

Other symptoms that can arise are the formation of urine crystals or bladder stones, also called uroliths. These can be quite painful, cause agitation and abdominal pain. Urine blockade is an extreme case scenario. Unchecked and ignorant attitude towards these conditions can be fatal.

Like all long term diseases, the formation of urine crystals begins as a slow and steady process. This is easily and readily treatable if detected at the right time. It can become deadly and can even lead to organ failure over time.

Other urinary problems and related conditions in cats are:

  •       Bladder or kidney stones
  •       Bladder infection
  •       Upper or lower urinary tract infection
  •       Kidney disease
  •       Excessive or not enough water intake
  •       Stress
  •       Poor diet
  •       Spinal cord issues
  •       Congenital abnormalities (birth defects)

Urinary Problems Causes

Since urinary crystals and bladder stones are some of the most common and problematic conditions in a cat, we’ll talk about them exclusively. These are formed when more mineral deposits like magnesium, calcium, and phosphorus or even protein are present in your cat’s urine.

The urinary system malfunctions or fails to get rid of these accumulations effectively. This leads to the formation of these crystals and stones. They’re physical entities that keep on piling up, becoming bigger and firmer with time.

That is why small conditions begin to compound and get worse. This can arise even the healthiest of felines. It has a lot to do with their diet and daily food intake.

How cat food helps

Many vets agree that water regulation can be the solution to the bigger part of the problems that arise. Therefore, it does matter in the long run what kind – wet or dry cat food, you choose to give to your cat. Wet cat food, naturally is given higher regard.

While dry cat food may be great for many other conditions like an upset digestive system, it may not be the best thing for a urinary tract infection. For starters, dry cat food has high binders. They’re loaded with fibers and minerals. Also, their moisture content is low.

Cats don’t feel thirst like we do, so it can be hard to help them when it comes to adequate hydration. Wet cat food is a great option, and perhaps in serious cases, an absolute necessity for the sake of your cat’s well being. Wet cat food has a high moisture level, and pH balance can be maintained much more carefully.

High pH acid levels in the body can cause acidic urine. Imagine how awful it would feel if it burned when you peed. Ouch! That’s exactly what your cat may be going through. While hydration is a good start, other contents and their balance matters a lot as well. Check your cat food to make sure that it lowers urinary pH and contains low magnesium

Frequently Asked Questions

How do I get my cat to drink more water?

Cats like to drink from running water, which is why they are seen to be interested in drinking directly from taps or fish bowls. Keeping fresh water bowls in different areas of your living quarters is also a great idea. Cats are curious by nature; switching places of their water bowls will keep them curious.

Cats are also surprisingly clean creatures and prefer fresh food and water. They’re high maintenance that way. Day-old water will likely remain untouched. Get a kitty fountain. It is a great way to maintain interest and get your cat to drink water.

Can dry cat food promote urinary health?

Yes, but it may not be the best thing for your cat. Keeping your cat constantly on dry cat food will eventually lead to higher chances of it contracting a urinary tract infection or disease. The drier the food and less the water intake, the harder the kidneys have to work.

It is ideal to maintain a balance between wet and dry cat food so that whichever content is missing from either gets taken care of. But feeding your cat both version of the cat food, you are allowing its body to process the best of both worlds.

We recommend wet cat food if possible. Dry cat foods tends to be more of a budget option, so go with that if you want to save a few bucks. If you want balance, try mixing your foods.


Our overall favorite cat food for urinary crystals is the Purina pro plan focus. It hydrates your kitty, helps lower urinary pH, and lowers magnesium so crystals don’t form.

If you want a more budget pick, we recommend the Purina One urinary health food. It’s a dry food, but it helps your cat lower urinary pH and stops crystals from forming.
