I have two cats that have troubles with UTI's. The vet suggested the prescription diet food. However, I have one cat who is allergic to any type of Corn ingredient in foods. Any foods I've found that are for UT health, they have corn in it. The vet gave me treats which the other's love, but one doesn't and won't eat them. Most treats for UT health come in small packages and are costly. Is there maybe a dry food out there that doesn't have corn and helps prevent UTI's that's not ungodly expensive? The vet suggested I get a water fountain. It would attract them to drink more water. Which I am going to get soon. But I was hoping there would be a food that I could put all my cats (5) on. But am having a hard time finding any! I'd be willing to do a treat of some kind, but I'd have to be able to purchase it in bulk and each pack would have to hold enough for 30 days. That is what I'm finding hard to do as well.
