Bowl shape
Whisker-friendly bowls are real for some cats because wide shallow bowls reduce face contact, but they are not magic.
The practical question is simple: does your cat eat more calmly from a shallow stable dish with the same food?

Wide shallow dishes make it easier for some cats to reach food without pressing their face into high sides.

Food pulled onto the floor, pawing, backing away, or leaving edge pieces can make a shallow bowl worth testing.

A cat may avoid food because of freshness, texture, stress, nausea, or mouth pain, even in a perfect bowl.

Use the same food, same amount, and same location for a few meals. Keep the bowl only if the cat eats more comfortably.
Use bowl gear that makes comfort, mess, and leftovers easier to judge.
