I want to start cleaning my two cats teeth, however, every time I have tried in the past they have not allowed me to get my finger in their mouths far enough to get that itty bitty tooth brush in there. Last time I took my one cat for a check up, the vet looked at his teeth, noticed plaque build-up but didn't even attempt to remove it. I was rather annoyed. Any other vet I have had prior has done that. I want to make it a routine cleaning their teeth, but they make it impossible. Does anyone have suggestions on how they accomplish this? Can you please help? Thank you.
