Felix's teeth aren't too bad. He does have some tartar on them and mild gingivitis. But that's only because sometimes I forget to brush for months. His breath has also improved since I've been brushing everyday. Is there anything else that can help with the tartar and gingivitis? Maybe a specific brand of toothpaste, an herb, drink, or something? I currently use these: ARM & HAMMER™ Advanced Pet Care Cat Toothpaste & Brush Set | cat Dental Sprays & Toothbrushes | PetSmart I just need something to loosen the tartar enough for me to remove it. His tartar never gets hard because I always pick it off before it gets "permanent".
