I love my kitten, but his breath smells like something died, farted, and started to decay. His gums are a healthy pink and there isn't a build up of plaque. I don't know what to do. He eats a healthy organic diet, gets plenty of exercise, and LOVES to drink water. He hates dental wipes or the vet prescribed drops. He runs away and hides when he sees them. What could be causing this? What should I do?
