Researching everything related to healing cat urinary crystals, & came across an old veterinarian who said that they had always used Methionine Amino Acid. It is sometimes listed as DL-Methionine. It can be purchased from Amazon /online /OTC. Both powder & gel forms. It ACIDIFIES the urine, preventing formation of Struvite Crystals. Most cats appear to have this type, as ACV is helping many. This is even better. Cats remain on it & have remission of problems. The powder is a much better price. If this information saves my kitty, & yours, I will be pleased. This, from an old vet who put old wisdom ahead of modern costly methods. I would add, read all ingredients labels. It would be smart to avoid any additives that say Phosphorous, Magnesium Stearate, Magnesium or Calcium anything. These only add to the problem. Having a good water filter that removes Fluoride from water is also important. There's little doubt in my mind that this problem is from additives to food, water, clumping & crystal litter, & harsh ingredients in medicine. Also~~ AVOID Bone Broth. AVOID clumping & crystal litter. AVOID dry cat food. The special diet foods for cats does not include the additives of phosphorous, magnesium, & calcium, & it DOES include METHIONINE in small amounts. That's why it works at all.
