My kitty Xen, as posted earlier, has a problem with constipation. Though he is on laxatives and canned i/d, I can't get him to drink water to save his life...literally. The vet thinks increased water will help. I have tried her suggestions of adding a little tuna water, ice cubes, and low sodium chicken broth but Xen isn't buying it. I haven't gotten one of the fountains yet because I've heard mixed things. Anyone have advice? Thank you so much!
