I have cats with extreme sensitivity to developing UTIs. I was told to feed the $$ Hill's Prescription stuff, but discovered a few things.
1. Cats aren't good water drinkers. Their tongues are not great at lapping up enough water to get their daily requirements from just a water bowl, and they are designed to get their moisture from their food. If the moisture content of their food isn't very high, they'll have kidney/bladder/UTI issues. Could also develop crystals (deadly in boy cats, painful and can cause issues with both sexes). So dry kibble exclusively is a bad idea. I feed dry kibble in the morning for my own convenience, but they get two other meals at dinner and late night snack that are wet cat food slurry (I add extra water to their food to make a soup/slurry) with some kibble on top. They LOVE this. They have lots of clean water available, but it's important for them to get water content in the food they eat because that's the way they were designed. One vet I came across in my research had a cutesy phrase: "Dilution is the solution to pollution." Which means if your cat is subject to any issues with kidneys/bladder and developing UTIs, more water is a good idea. And that really does mean trying to feed less dry kibble and more wet meat-based food.*
The kibble is Purina One urinary tract stuff. It's low moisture, but higher acidity to avoid crystal formation. It is still crappy dry kibble (there are no great dry foods, period), but it's there to make things easier for me and won't hurt my cats as long as I'm measuring their food intake and make sure they're getting their wet food as well. No more vet visits since starting this feeding schedule, and their coats/health are all fabulous (soft, shiny fur and very active/alert).
2. I get store brand wet food, but I usually get the chicken or turkey flavors and I've read the ingredients to check that the protein and moisture ratio is high while the carb/filler ratio is lower. Some of the canned foods use fish as a base no matter what the professed flavor, but in studies I've read, feeding cats fish is not so good for their digestion/overall health. So I do poultry pretty much all the time. They don't care. The fancy brands that include veggies and such are just gimmicks; cats are carnivores and don't need grains or veggies or fruits at all.
3. No free feeding. It is not good for your pet; it just makes things easier for you, but your pet will suffer most of the time. Sure, wet food is a pain to dish up and clean up after and you can't leave it out and it smells... but it's the healthiest option for your pet, even if you're not feeding them the fancy $2/can brand stuff. Most all my cats LOVED dry kibble because they could graze and it was super convenient for me since I didn't have to do much but throw a cup of food in the bowl every day or so, but cats tend to get fatter with free feeding, all those carbs are terrible (and almost all the kibble is going to be grain or crappy fillers even with the $$ for the expensive bags) and nutritionally speaking, dry kibble is just not good for them. It is the equivalent of getting a frozen pizza when you're tired after work instead of making a healthy dinner with a good serving of lean meat and veggies for yourself. Sure, a few times here and there isn't going to hurt as much but you know you shouldn't be eating that stuff all the time...
So I have to measure using tablespoons/measuring cups and make sure to feed the right amounts for each cat based on ideal weights and read the labels and calculate the calories per ounce. It's sooooo fun. /sarcasm (but what's really fun is that my cats are no longer fat blobs, shiny and active, and are not crying in pain or peeing 20 times an hour or worse, at the vet's office for emergency surgery that costs me $$$ each time)
*If you have a cat with kidney failure, it is a delicate balancing act to get less grain and more protein but not so much high protein that it stresses their kidneys. This part sucks, and really should consult your vet for help on foods if there are serious medical issues like this.
