Cat stones can be fossilized by taking medicines containing methionine, ammonium chloride, acid sodium phosphate and other ingredients. There are several types of feline urinary stones. The most common one is magnesium ammonium phosphate crystals. Magnesium ammonium phosphate crystals cannot form in acidic liquids and will dissolve, so they are usually treated with related drugs.

Cats suffering from stone disease should eat prescription food, which will help the cat recover and allow the cat to drink more water to relieve the pain. If your cat's stones are very serious, he will need to go to the hospital for surgery to remove the stones. If your cat does not urinate for 2 days in a row, you need to see a doctor for catheterization.
