There are probably others but I'm definitely one who has a cat with bladder issues. I haven't read the article but the vet told me Tucker has to drink lots of water so I started putting a bowl of fresh water in my bedroom. Since I did that, all of them have been drinking a lot more water every day. I usually fill the bowl in the morning and then refill it at night. When I do, they run to get to the water first. Tucker went on special cat food a month ago so they all get it. I wonder if it doesn't have something in it to make them thirsty because they never drank this much before.
