With all the replies about brushing, I didn't see the answer to the question--- just how to brush and with what. I have yet to find the perfect toothbrush for the tiny ferret mouth. I'd like to see C.E.T. make a very small extra soft version of a human baby brush. The short handled cat brush is close but too stiff (run a brush on your upper lip and feel how stiff) and not the right shape to get in the back of the ferret mouth. Does anyone have any better ideas? My ferrets all like the poultry flavored enzyme toothpaste from C.E.T. What about the enzyme water additives? What happens when the are ingested? Some of my gang drinks from a crock which is changed twice a day. I'd be throwing out a lot of the product. Thanks, Carol O. [Posted in FML issue 4115]
