I thought I did good, when we adopted our little guy from the shelter. Got him a fountain with filter, he liked it and drank from it. Migrated him to Blue. Thought it was nice, high protein, grain free, not the cheapest but reasonable. Looked good. Then he had hilarious gas. So read that fish is easier on stomach. So it was Blue Basics Fish recipe for several months. He filled out, coat got glassy and nice, everyone was happy.
Until he got a UTI and blockage =(
Now reading I realize we need canned food for moisture content boost.
And that fish is the worst due to higher bone and thus phosphorus/calcium/magnesium crystal forming minerals.
He's on Royal Canin SO cans by order of vet. But looking at the ingredients and feel like I am short changing him on diet quality.
Weruva looks like one of the best options. Chicken Frick a Zee especially seems perfect.
Grain free, 67%protein 25% fat excellent
2.7% carb, almost a diabetic formula, but some say low carb promotes proper ph balance to prevent crystals as well.
.81 phos really low
.07 mag is almost non existant
"Fish is easier on the stomach"? I've never heard one before!
Well reading your intro, it looks like fish based kibbles were the biggest cause of your problem, but you've learned a great deal.
You want to look for high protein (no seafood), but one that is mainly animal based protein as meats
tends to be naturally acidic. Food with lots of plant based formulations are a problem, in my opinion. These days companies add in peas, tapioca, potatoes, carrots, etc. While sounds great to the average consumer, do carnivorous cats need them? I hardly think so.
Here's a link to help you search for more quality canned food by one of my local independent stores in my area. One of the best resources for finding good quality pet foods can be found in your small, privately owned pet stores. They always provide me with excellent service, competitive prices (compared to big box pet stores), and even have a rewards program. The staff who work there are all quite informative about products they sell, quite a big difference from those big box pet food stores.
