Has anyone else ever had any problems with tartar build-up/cavities with their ferrets? I recently noticed that two of my boys have dark marks on their back teeth. I don't know if it's just tartar or (I hope not) cavities - they won't let me have a real good look. I did manage to scrape at the tooth of Nik and he didn't seem to be in any pain, just a little ticked that I was messing with his chompers. I have heard others talk of treats that they give their carpet sharks and we don't give them much in the way of sweets and such, except a few raisins a couple times a week. I made an appointment with the vet to have them checked out - should I be overly concerned and how could I possibly avoid this problem in the future?? Should I think about also adding Milkbones or the like to their treats or are doggie treats like this a bit too hard for my boys?? Thanks in advance for any information you can pass on - Gushi, Nik & Buster!! (oh and George too!) [Posted in FML issue 0667]
