Not for Cats
I used the smaller toothbrush end but it was still difficult to use on my two cats specially the adult cat that has the small mouth. The back molars were hard to reach with this toothbrush and I ended up scratching their gums a few times. Switched to the Virbac C.E.T. Cat Toothbrush which has been easier to use since it has very long bristles to reach the teeth and a much smaller round head which prevents the hard plastic from injuring the gums.
