Our cat, Gypsy, is about 12 yo. We took her to the vet last year because of increased water intake and urination. Thought she had diabetes. Testing was negative. They put her on a special diet and sent us home. I was concerned about her kidneys and high urine output. After much research, I came across Davinci Labs UT Support for Cats. Within 2 months, Gypsy's urine output returned to normal. As long as she stays on the UT Support, she remains well. I tried another product but it doesn't work as well. I highly recommend this product.
