If you’re noticing bad breath when you’re around your cat, we’d like you to make sure you tell us about it! Bad breath is not normal and is the number one symptom of dental disease in dogs and cats. Other symptoms of Dental Disease may include yellow or brown colored teeth, red swollen gums, pawing at the mouth, drooling and having difficulty eating. If you see any of these things, it’s time to schedule a dental cleaning for your pet.
