My cat bonks her teeth on the bottom if there isn’t a Protective Layer of Kibble^tm^ on the bottom. I switched her to a silicone toddler plate ( www.amazon.com/gp/product/B07FK341WP ) and she doesn’t have that trouble.
But also- stale greasy meat crackers, covered in dried cat slobber < fresh greasy meat crackers, not covered in dried cat slobber.
The toddler plate with a meal sized portion, cleaned after each use has eliminated kibble waste and fussiness.
