YSK: Cats don't like their whiskers touching their food bowl. This is why they beg even if food is still left at the bottom.
Whisker fatigue causes stress and overstimulates their senses. Using a flat bowl or plate will relieve this issue and allow your cat to eat all their food without stress.
You can also search for "whisker fatigue" bowls specifically made for cats.
Sorry, but this is pseudo-science bullcrap akin to healing crystals. Whisker fatigue is just some BS a mom group on Facebook came up with to sell products. It has zero scientific backing and frankly I would appreciate not spreading false information like this here. Leave that garbage on reddit
My cat will only eat from a bowl when there is Amethyst and Rose Quartz crystals arranged to promote calmness, love, and emotional healing. It is literally science.
