I brush my 5 ferrets teeth every night with the small C.E.T. cat toothbrush and Oxyfresh Pet Gel. I have three 5-year olds and 2 younger ferrets whose teeth and gums are beautiful! I am very commited to this because I've seen a huge benefit in the health of their mouths and I really appreciate not having the stress to myself and them of an anesthetic & teeth cleaning!
