Would you consider getting a cat drinking fountain? Sometimes cats get crystals when they don't drink enough water, and many cats prefer to drink running water. It's good to get a rubber or plastic mat to put under the fountain, as many cats enjoy playing in running water as well!

Another thing you can do is serve them canned food with extra water mixed in. Smudge also gets a supplement called Cosequin mixed into his "salmon mousse" that strengthens the lining of the bladder, and is helpful no matter what kind of crystals a cat is contending with.
