Holy cow. Our kitty does the same thing. He has a silver bowl and eats down the middle. Once any silver is showing —- STOP. Looks up. Meows.
He also will not drink water left in his bowl over 8 hours. Shows difference between cats and dogs. Our dog will drink water from the gravel drive that has been sitting 3 days. The kitty - oh the horror!!!

My dog would rather drink out of a puddle than that nice clean water in his dish. He also won't get into the truck if he has to step into a puddle to do so... which isn't a bad thing.
