New kitty Fellini has the WORST breath ever. I mean, he gets two feet from you and meows or opens his mouth, and you want to die. What I can I do about this. He was at the vet, no bad teeth or anything. They are dirty, but how can I take care of that at home? Are there any products, techniques, brushing that I can do at home, minimal cost, and clean his teeth and make his breath better? He eats only hard food... And is about two years old... If that helps anything. His gums are healthy pink.
