Here is the dental info which Jules mentioned. It is from _Biology and Diseases of the Ferret_. Note that this means that having the adult canines in place is a great way to tell 8 weeks of age if the USDA proposed change in age of sale and transport goes through. See the IFC (International Ferret Congress) URL below my name in places currently working my brain for the project headed by Dr. Sandra Kudrak and a vet team with which she is working. Upper: 50 days (just over 7 weeks): Canine -- the conical shaped tooth Molar 1 -- 53 days (7 and 1/2 weeks): the tooth at the back which has a bit of flatness to it Premolars 2-4 -- 60 days (8 and 1/2 weeks): the slicing teeth at the sides of the mouth Lower: Canine and Molar 1 -- 50 days (just over 7 weeks) Premolar 2: 60 days (8 and 1/2 weeks) Premolar 3: 67 days (9 and 1/2 weeks) Premolar 4 and Molar 2: 74 days (10 and 1/2 weeks) Note that body size can be decreased by having trouble getting enough food so it is not a reliable indicator of age. Eyes open usually in about the fourth week but that can vary by about a week according to what some breeders have noted in the past.

Others are just neat.
