I'm not sure how to fairly review this. My cat had a suspected UTI, but the vet wouldn't give antibiotics until I got a urine sample (not an easy task!) I gave this for a couple days until the UTI was confirmed. It will not "cure" a UTI...he's on antibiotics now...but I do know he has not acted at all like he was in any discomfort. He has been eating, drinking, making biscuits, snuggling, and begging as usual. It is easy to give. Smells kind of meaty/savory, and I put it in a couple tablespoons of milk, and he laps it up along with the antibiotic. I am going to continue to give prophylactically, as both cranberry and d-mannose are very good at preventing UTIs. This is his first UTI (he's 5), and the vet tech said it could be a one-off, or this could be the first of many, so I can't say, "this product has reduced his UTIs from 3 a year to 0," but the ease of use and his lack of discomfort are enough for me to keep using it.
