I have a ragdoll cat and he had a leg amputated last year, since then we have had nothing but bladder issues with him and a trip to the vets at least every six weeks. Numerous doses of antibiotics really did not help, in desperation I went on line and found Yurelieve. WOW 5 days of treatment with Yurelieve and my cat is back to his old self, playing and not sitting half his life in the litter tray. We are now sure that his problem is cystitis as no evidence of infection has ever been found. I would stress that you should get your cat checked with a vet first to make sure there is no underlying problem before trying this product. I have purchased two more boxes as a standby and would recommend this treatment to anyone with a cat who has a long standing UTI problem. Thank you VetUK I no longer have to worry that I cannot do anything for my cat when he has this problem.
