Even if you elevate your cat's feeding bowl, you're only solving half the problem.
The other half? The material the bowl is made from.
If you're using a plastic bowl (and most cat owners are), you need to understand what's happening on a microscopic level.
The Biofilm Problem
Plastic bowls develop something called biofilm—an invisible layer of bacteria that forms in the microscopic scratches and grooves that develop over time. No matter how thoroughly you wash the bowl, this biofilm persists, creating a bacterial breeding ground.
The result? Feline acne (those black spots on your cat's chin), potential digestive issues from ingesting bacteria, and a general accumulation of impurities that your cat is exposed to with every meal.
Ceramic bowls are better than plastic, but they can chip and crack, creating new hiding spots for bacteria. Plus, many ceramic glazes contain heavy metals or other substances you don't want near your cat's food.
