My sister has lost many cats to UTI. She has since learned to make sure they drink lots of water and if they won't drink much than give them moist food.

My two kitties drink so much water you would think they have a hollow leg. LOL I am so glad all my cats were water drinkers. I have water in the bathroom for them and I if you get them a good supply of water they are more likely to drink. A fountain may be the best if your cat if finiky about drinking.

My sister has a little fountain by her fireplace. It's for decoration not a pet dish but her cat loves to drink from it and really likes it when it's running.
