We have 8 cats. Three boys have had issues with crystals - 2 of them were extensive problems. Our latest rescue has allergies.
We used to free feed dry, and supplemented with 1, then 2 wet meals a day. All regulated just fine - but the last 2 rescues were older ferals, and didn't regulate. The latest one also has allergies. So we had to stop free feeding because we had one fat cat, and one cat with allergies that couldn't eat the prescription dry we had down.
Two of the cats just did NOT switch to the timed wet food feedings. So I keep two bowls of kibble handy. One is Hill's c/d dry for the male (prescription food for bladder issues). I gradually started mixing in higher quality food to that because he is eating some wet food 4x a day, and I mix the wet with water, so his urine stays dilute. So the dry food brands I add to that are Instinct (grain free, chicken), Orijen (grain free), and Merrick Before Grain (chicken). The mix is 70% Hill's c/d, 10% Instinct, 10% Orijen, 10% Merrick Beforfe Grain.
The female gets Hill's Hairball. But she also eats some wet food 4x a day with water mixed in.
Two of the other boys (that had problems with blockages from crystals) eat primarily wet food, but when they "ask" for nibbles of kibble, I put the bowl down for them. They nibble a little bit - but again, both are self-regulators and at healthy weights.
We work from home, so I feed four wet meals a day.
The brands they eat are:
Instinct (Rabbit, Chicken, Turkey, Duck)
Evo (Venison, Chicken & Turkey, Duck)
Before Grain (Chicken, Chicken & Quail)
Wellness Pouches (Turkey & Duck, Chicken, Duck & Shrimp, Chicken, Crab & Herring. Re: Wellness, I feed only the formulas that use oat fiber, not potato starch).
Wellness canned: Chicken
Hill's c/d: Chicken
Our overweight cat gets a teaspoon of whatever canned we're giving, and 1/2 a can of Royal Canin ultra light (3.5 oz) at each meal.
I give them Fancy Feast (original formulas only - I don't give them anything with wheat gluten because of Chumley's allergies. All Fancy Feast in gravy has wheat gluten) and baby food occassionally as a treat.
Four of our cats are 9 this year, one is 8, one is 6, one is going to be 5 this year, and one will be either 4 or 5 this year.
They are not active cats. I split one can of 5.5oz food between six of them (one weighs 7 pounds, one weighs 8, three weigh 11, one should weigh about 12 - he's a little over that, but it should start coming down slowly now. I hadn't factored in the calories from the pill pockets he needs); and I give the overweight cat and the cat eating primarily dry about a teaspoon/tablespoon (respectively) out of that can at each meal, and they split the Royal Canin Ultra Light (it's the only wet food the not overweight cat really likes and will eat all of). Because of the pills the 4/5 year old (the one with allergies) requires, he gets an additional 50-60 calories a day from his pill pockets (I try to use less than a pocket per pill).
Other than the two wellness pouches and the Orijen dry, I avoid seafood ingredients (minor components in the foods I'm feeding at a minimum).
The outside ferals eat 4health dry food (all life stage) and get either Science Diet Kitten wet 2x a day, or Fancy Feast (whatever's on sale).
My DH thinks it's complicated.
