My cat has urine crystals. What food lowers pH and prevents them?

The best and most effective treatment to adjust a cat’s urine pH is to start a special prescription diet. Royal Canin, science diet and Purina all make prescription diets with additives to make the urine more acidic. This will also help to prevent urinary tract infections. These diets can be purchased in many pet stores and online as well but they do require the OK from your veterinarian. The diets will begin to take affect within two weeks and it is recommended to retest the urine one month after starting the new diet. I hope this helps.

Thank you for submitting your question regarding Speedy. If his veterinarian has recommended a prescription diet, then he should stay on one. Royal Canin Veterinary Diets Urinary SO, Hills Veterinary Diet C/D or Purina ProPlan Veterinary Diets U/R are all great choices to help prevent crystals in his urine. I hope this information helps!

Yes it is. That's because it helps dissolve crystals and has properties to increase urination and prevent further crystals from forming. If Coleman does have urinary crystals, I highly recommend feeding him this food.

I would strongly advise against this. I would keep him on some form of food labelled for urinary crystal prevention. Urinary blockages can be a fatal emergency. Royal Canin, Hills, and Purina ProPlan are the three foods that use the most science in their nutrition. I have never heard of young again. Any of their foods that are labelled "S/O" are meant to prevent the formation of urinary crystals. Many urinary diets do have an increased caloric amount, and I sympathize that can be a struggle, but it is related to what keeps their urinary tracts healthy. You can try feeding canned food that is watered down to lower some calories. The extra water and hydration is great for the urinary tract as well. Feeding the food out of toys and feeders, instead of bowls in meals, to encourage their working for food and hunting behaviors can also help with their food intake.

From Royal Canin's website: "This diet is only suitable for healthy adult cats that do not have a urinary issue or a history of urinary problems. This food is not a replacement for a diet prescribed by your veterinarian." If Elbi has already had a urinary problem, I don't recommend considering switching to the urinary care food. Urinary S/O is designed to encourage more drinking, as well as neutralize the pH of the urine - both of those together tend to almost completely eliminate the chances of crystals forming.

Purina Friskies is a low/mid grade quality food and I would not be surprised if his crystalluria returns. He really needs a prescription diet such as c/d from Hills or a similar formula from Royal Canin. Your veterinarian should have this food available, or be able to send you to a store to purchase with a prescription. I have also had good luck using Crystal Stone Formula ( a Chinese herbal), but this is a prescription herbal. I would be happy to consult with you about this. I would recommend a prescription diet for at least 6 months prior to trying to wean off of it. If you absolutely CANNOT get a prescription diet, I would focus on a high quality, high protein diet, but NONE will dissolve and prevent crystals as well.

Thank you for submitting your question regarding Beatrice. Royal Canin Veterinary Diets makes a prescription urinary diet as does Purina ProPlan Veterinary Diets. These options may be better for her if the current diet is not helping the crystals. This should be verified by frequent urine examinations. Adding more moisture to her diet through water or canned food will help dilute her urine. This will help as well. I hope this information helps!
