I'm so glad I have FML to turn to with my many ferret questions! So I just recently began brushing my ferrets teeth. I didn't earlier in their lives because someone told me (not from FML) that brushing teeth was only necessesary in older ferrets. After reading up I found that really isn't the case and started anyways. It appears I'm too late though. My ferrets aren't old (one is over a year the other is under a year) and they're on a good diet. (EVO and some diluted furotone for a treat) Still, while brushing their teeth I noticed some dark greenish buildup on the very back teeth. I tried to scrape some of it off but they wouldn't hold still so i'll have to try again when someone can scruff them for me. I'm using marshall's dental gel for their teeth and i usually use a rag till I get a fingertip brush (need to pick one up, unless you guys know of something that works better!) I just want to know what this is and if this is serious and requires a vet's attention or can i solve this problem myself? [Posted in FML 7093]
