If you are currently feeding a diet of dry cat food, make sure you are taking some extra steps to make sure your kitty is getting the moisture they need. In the wild, the prey they hunt and eat is at least 70% moisture. The typical kibble dry food is 5-10% moisture. Combine that with their low thirst drive and we have a lot of kitties not getting enough moisture in their diet.
Cats who struggle with dehydration can develop kidney issues from urinary tract infections (UTIs).
