Cats with bladder stones will be all over the place with their urination habits. If your fuzzy friend is straining to urinate, urinating outside of the litter box, has discolored urine, has to pee a lot but not much comes out, or is spending all day licking licking his genitals, these are all signs that bladder stones are afoot. Head to the vet immediately.

Male cats are especially at risk of dying from toxicity because their ureter is more likely to become blocked. In the words of Dr. Jennifer Coates “This is a life-threatening emergency that needs to be dealt with immediately; in other words, not when your regular vet opens in the morning.”


When you do make it to the vet, they’ll have an arsenal of tests ready to help diagnose your loved one. A urinalysis may be conducted to identify any mineral imbalances in your cat’s pee, and x-rays and ultrasounds can be employed to get a visual on the stones.


A urinary tract-friendly wet cat food will be your cat’s best friend when she’s trying to recover from a bout with the evil stones. Bladder stones are more easily broken up and passed when your cat is properly hydrated.

A wet cat food that’s engineered to treat the stones will hydrate kitty while supplying the right combination of vitamins and minerals. Supplementing with dry cat food that’s low in magnesium, phosphorous and calcium will also help to pass the stones and prevent their return.

Make sure to get a urinalysis done to determine what type of minerals the bladder stones are made of. Stones made from struvite deposits account for half of the cases and are the easiest to treat nutritionally. They can be dissolved with a diet that’s low in phosphorous and magnesium.

Half of the cases are due to stones formed from calcium oxalate. These are best treated with a low calcium diet. There’s also a small percentage of cases that improve with a low protein diet.

If the stones can’t be broken apart and dissolved through diet, they’ll have to be surgically removed or blasted apart with ultrasonic shock waves.

Prescription grade cat food without the prescription? Sign me up! Personally, if my own little fur dumpling had bladder stones, I’d feed him a combination of Hill’s Prescription Diet Urinary Care formula cat food paired with our “Top Pick” from Royal Canin.

According to customer reviews, this Hill's product is especially effective at breaking up stones within 1-2 weeks. If you find through your cat’s urinalysis that the stones are from struvite mineral deposits, choosing Hill’s is a no-brainer. Struvite bladder stones can be easily treated through diet.

The secret is in the food’s controlled levels of calcium, magnesium, and phosphorous. It’s important to keep levels of these minerals as low as possible without becoming deficient.

Hill’s also adds additional potassium and vitamin B6, which helps to interrupt the formation of new crystals.

The omega fatty acids in the fish oil they use help to soothe inflammation in the bladder that accompanies the restriction of urinary flow.

Stress is also known to exacerbate urinary issues in cats. That’s why Hill’s has added L-tryptophan to help manage stress.

All in all, this is a fantastic option for any bladder stone attack plan.

Your cat isn’t likely to have a huge appetite while suffering from bladder stones. That’s why an extra appetizing cat food can go a long way in helping return kitty to baseline. Cats can’t get enough of Urinary SO. Canned food helps to break up the stones while keeping kitty hydrated.

By choosing to feed your cat a premium wet food like Royal Canin, your kitty will be blessed with an increased urinary output from the additional fluid she’s getting. Urinary SO, however, doesn’t stop here. It boosts urine output even further with the help of extra potassium and chloride.

Protein is a necessary part of a cat’s diet, but in a small percentage of bladder stone cases, the problem can be made worse by low-quality protein or too much protein in the diet. Urinary SO goes the extra distance here. They use an optimal amount of only the highest quality protein to ensure that everything is being done to heal kitty from the inside out.

As with all urinary formula cat food, Urinary SO contains very little magnesium, phosphorous, or calcium, which are the minerals from which most bladder stones form. Their recipe also helps to keep the urine slightly acidic, which is ideal for the prevention of stone formation. Get out of here stones!

I ran into several reviews from pet owners who feel that the food helped save their cat’s life. Bladder stones, especially in male cats, are nothing to be taken lightly. The risk of death is real, and the onset of life-threatening conditions is fast if their urethra becomes entirely blocked by the stones.

- Cats love it

- Extremely effective

Hey, I get it, not all of us can afford to go out and buy the most premium brand of cat food every time our cat gets sick. Luckily, Purina Pro Plan Wet Food offers similar benefits to Royal Canin Urinary SO, but at a lower price point.

Cats, even ones with poor appetite, gobble this stuff up. That’s fantastic because the moisture in this cat food will go a long way towards rehydrating kitty by helping him pee with more gusto.

This food's low magnesium content helps to break up and prevent the formation of struvite crystals that cause bladder stones. Purina doesn’t go out of their way to claim a low calcium content, but there's nothing in the ingredients that suggest it's particularly high in calcium either. This is ideal because approximately half of bladder stone cases form from calcium deposits.

One of the few drawbacks is that they don't use the same grade of premium protein that Royal Canin does. This isn’t to say that the quality is bad. They use real chicken and avoid the use of fillers. When it comes down to it, Purina Pro Plan Urinary Tract Formula is an effective way to reduce urinary pH and help prevent the return of bladder stones.
