I have a question I hope everyone can help with. My baby boy Pato (an 11 1/2 month old sable gib) has brownish stains on the "business end" of his top "fangs." It started on his left side first, then appeared on the right side. All of his other teeth are just fine, no build up of tartar, etc. It doesn't seem to be anything but unsightly, but I am concerned. Is there any way to get it off? He refuses to chew on bones or anything but soft drink tops and straws. The boys eat Kaytee Ferret Food, Ferretone and Ferretvite, raisins once in a while, and occasionally a drink of milk. I really don't know what could be causing this. Any suggestions? His health seems to be excellent, just these two little brown spots on the ends of the fangs. All the talk of ferret teeth lately made me hope that all of you people who are so knowlegeable might be able to point me in the right direction. Thanks, Catherine, Pato and Snowball (The "Dirty White Boy") [Posted in FML issue 2117]
