Rated 1 out of 5 by from won't eat Can't say it's the food's fault, but our cats turn their nose up at this formulation. I thought we would try another turkey choice with this shipment...but sorry we did

Rated 5 out of 5 by from I was skeptical at first My cat Elvis had a UTI and I thought by upping his water and feeding wet food only it would prevent a recurrence and any further issues. However he soon suffered a full blockage. After surgery, a week in the hospital, and a month of recovery at home he recovered 100%. The vet this time recommended a couple different RX foods, Purina Pro UR being the one Elvis took too best. It's been over a year on Purina UR RX and he acts like a completely different cat. Less timid, more loving, and playful. I believe it's all due to him now being regular/normal in the bladder and urinary areas thanks in a large part to this cat food. My other cat Priscilla eats it as well. The price is a little hard to swallow at first but well worth it. Other noticeable side effect/difference is way more pee in the litter box (which is a good thing!)

Rated 5 out of 5 by from good for them, AND they love it My male cat had some horrible urinary tract problems this spring and had to go on prescription food to keep them from recurring. I feed him this food mixed with a little bit of (non-prescription) Purina Pro Plan Focus Urinary Tract food. My female eats it, too, since there's no practical way to feed them separate meals. These two very picky eaters, who used to turn their nose up at everything after a few weeks, love this food. It's been 6 months now, and they still run for their food dish and eat every bite. All that, and no more urinary tract problems! Also, a quick word for Chewy's staff: I needed to modify an order b/c it wasn't going to ship in time (the vet didn't respond to a verification request). Chewy's got the vet to approve AND got the shipment to me in time, after all. And they were incredibly pleasant on the phone. I'm sold!

Rated 5 out of 5 by from Recommend with a Question My siamese guy has been on UR dry for a year now with no problem. I got him a can of this UR wet today and he gobbled down half the can like he was starving!! I don't know how much to feed him -- he gets a half handful of dry and 1/2 cup. Have to research and find out.
