Hello.
Welcome!
You have found the best place for help and support.
Here is a link to the food lists. Most of us here choose foods that are 10% carbs or less. As Dr. Lisa Pierson advises on catinfo.org , the best diet is
raw or partially raw. That would have no carbs and is the most natural for cats.
But not all of us can get our cats to switch so the lists below are the canned varieties. Dry food for cats is so overloaded with carbs , even the specialty
prescription diets for diabetic cats. It's just like jumk food for us. And we know better than to sit around and eat cheetos and poptarts all day.
well, maybe not. And now we're feeding our pets the same way without realizing it.
No one likes the Hill's dry. It's way to high in carbs. Too many vets blindly give it out.

You don't have to get the most expensive canned food, there are cheaper options like fancy feast
classics.
And there are some from walmart on the list that many here use.
Dr. Lisa has great advise if you have a dry food junkie but most cats are willing to switch.
You have to also get out of that habit of leaving dry food out for convenience. If your cats like the canned right away then take the dry food away completely.
It's the best thing you can do.
Using fancy feast as an example, with 3 cats , you would be feeding each about 3 cans a day ( for a 12 1/2 lb cat) as the cans are only 3 oz each.
It is also better for your cat if you can break up to several small meals a day. It's better for their blood sugar than feeding twice a day because it becomes feast or famine for their bodies for hours.
Many here who have to work all day freeze portions to leave out and let thaw ( which in your case would mean the cats are separated since you don't want to
cross feed).
We also like high protein only treats which are given out mostly during the glocose testing with a home monitor.
There are a few out there. They are harder to find. Just look for onces that say 100% protein.
I like one call PureBites .
comes in shrimp, liver, chicken and fish. I hear they are bringing out a turkey.
Here is the cheapest place I've found them.
