Not used yurilieve. My Frodo has a problem with cystitis. His is triggered by food with veg or cereal in as it makes his urine alkaline. Feeding a raw diet stopped the cystitis. But now he is 15, after being on raw for 11 years, the cystitis started again after the vet told me to put him on a renal diet. I put him back on the raw and gave him ascorbic acid to change his urine back to acid. The cystitis stopped. It was awful on the renal diet, peeing frank blood and crying out. Because I give him meds for the CKD, it tends to make his urine alkaline again. So as a precaution, I give him vitamin C twice daily. It has to be the ascorbic acid version as that turns the urine acid. Being water soluble it is quickly washed out of the system with a cat drinking a lot. Hence giving it twice a day. But of course each cat is different. I know what triggers Frodo's, and luckily am able to control it. As well as the vit C, he also has Denes greenleaf capsules, and Denes kidney support twice daily along with his Renalzin for CKD. I also have just started giving him on Kitzyme healthy cat with zinc and cranberry. There is no evidence cranberry helps cats with urine problems, but as there are other things in it to help the immune system, I guess at least it won't harm.
