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

Updated On September 23rd, 2025

Pet's info: Cat | Siamese | Male | neutered | 10 months and 14 days old | 8 lbs

My cat currently had blood work/testing for a check up before neutering. I was told he has crystals in his urine, and high pH levels in his urine also. Is there a diet, or specific foods I can feed him to lower the pH levels (his pee smells so strong, it's yucky)? What will help to stop the crystals from forming? Maybe some vitamin supplements? I'll try anything. Thank you!

What a cute kitty! Your vet can prescribe a special prescription diet to help manage the crystals in his urine. The one we commonly prescribe is Royal Canin SO diet, but there are several others available as well. These diets help keep the urine pH at an appropriate level and can decrease or eliminate the crystals in the urine.
