What can I do for my cat’s teeth? My cat has yellowed teeth and bad breath. His gumline is also red around some teeth. He’s eating and acting normally, but I’m very concerned about his teeth. It’s difficult to get a veterinary appointment where I live due to the pandemic so I’m only able to take him to the vet a month from now. Until I can take him to the vet, what can I do for a month to help his teeth?
