When cats do this (complain that the bottom of the bowl is empty), it's typically because they don't want to shove their face (and wiskers) into the edges of the bowl

Its called "wisker stress"

A shallower bowl (or just a small plate) is usually more comfortable for them to eat off of

Alternatively, they might paw the food out of the bowl then eat it off the floor, for the same reason

I just got an autofeeder for my cats. Wonderful thing. My cats still come to me and sit and scream for food for the hour before each mealtime, and we argue about whether or not they currently need my participation in mealtime, right up until the thing kicks on, then they're off like a shot. It's hilarious.

Hey, just to throw it out there: kibble isn’t great for your cat. Cats should get most of their moisture from their food, so moist meats are best. They’re obligate carnivores. Those teeth are not made for chewing hard biscuit things. They love it because it’s basically junk food. But it contributes to kidney disease due to dehydration, tooth decay by age three because of the starches activating with the enzymes in their saliva, heart disease because of the weight issue and nutritional deficiencies (not to mention, cats will eat until they have sated their appetite for nutrients, hence why cats who eat kibble always seem to be hungry), along with a slew of other issues because everything good about the ingredients is extruded out in the process and they spray artificial vitamins back onto the food.

Like…don’t feed your cats kibble. Put it on top as a little crunchy garnish, nowhere close to the same amount of harm in that. But give your cats wet food with actual meat (not byproduct) as the first ingredient. Or better yet, buy your cat some raw food like primal, small batch, vital essentials. They are enforcing high pressure pasteurization in the industry, which is a shame because it has some of the same effects on the good bacteria in the food which helps maintain gut health, but it’s still way better than kibble. Cats are small, they really don’t eat a whole lot. Splurge on their food and you’ll save on vets bills.
