Hi,
I have a snacky cat too.
I would suggest you grab a few cans of fancy feast ( classics are lower in carbs, avoid gravies which are higher) until you have time to read up and search the
janet and binky food list.
The turkey and giblets is 7 carbs, supreme supper is 7 carbs, and 9 lives flaked tuna in sauce is 2 carbs, (29 fat) and 9 lives ground turkey and giblets is 6
carbs.
These are some that are easy to find at any old grocery store while you research.
I would definitely feed more often expecially during the adjustment period of getting rid of all the dry kibble. There's a chart here somewhere about how many
calories a cat should have based on their weight.
You won't likely find any pure protein treats at a grocery store but look for PureBites freeze dried treats (shrimp, chicken, beef, I hear turkey is new)

Check out other foods from the binky list to get the free shipping.
Many specialty pet stores are getting in new products that are freeze dried treats.
I also give my cat a real shrimp sometimes after a shot. She loves shrimp and crab meat, not so much on fish.
And there is also cat-sip milk for cats. No carbs. Low fat lactase. No sugar.
These are often rewards or snacks because I know she's a little hungry.
I'm looking at getting the timer food dish because right now I'm waking up in the middle of the night to give her a freeze dried piece of chicken to
ease the edge. 8 hrs is a long time for a cat with barely any carbs......
This is all kind of like the south beach diet. They had you eating no carbs, and lots of high protein snacks. Eating those snacks keeps you from feeling hungry.
