Filou had the tooth cleaning procedure 3 times up to now

I have been talking to my vet about tooth brushing but she says to her opinion you can do it with very few cats (and Filou isn't one of them ). She says if I force my cat daily to have his teeth brushed this will influence our relationship more badly than a tooth cleaning every two years.

And I know how Filou can go to the fifth dimension whenever he needs some medication
