With all of the positive reviews I was very hopeful for ACV. Our cat was using the litter box, but straining to urinate. It was the weekend - of course. I gave him some canned food with ACV on it and he ate it, also put a couple of drops in his water. The problem progressed into a full blockage and now he's at the emergency vet. Will have to stay for 1-2 days. I'm glad this has worked for so many people, I wish it would have for us.
