both of my cats are 1.5 years old. 1 of then had a dental only at 14 months old. 2nd cat now has mild gingivitis. I bought virbac toothpaste, poultry flavor, as recommended by the vet. they tried as a treat and were ok with it, didnt hate it. how many times a week is good? i was thinking 1x a week since both cats teeth arent that bad. do people/cats prefer finger, finger brush or a toothbrush? how much brushing is good enough? like what if they just want to eat it like a treat? or if i rub some some around their teeth and gums and let them do the rest?
