You get the picture. Now, >compare that with the below table of typical eruption times for >ferret teeth: >Upper: >***50 days*** (just over 7 weeks): Canine -- the conical shaped tooth >***53 days*** (7 and 1/2 weeks): Molar 1 -- the tooth at the back > which has a bit of flatness to it >***60 days*** (8 and 1/2 weeks): Premolars 2-4 -- the slicing teeth > at the sides of the mouth >Lower: >***50 days*** (just over 7 weeks): Canine and Molar 1 >*** 60 days*** (8 and 1/2 weeks): Premolar 2 >***67 days*** (9 and 1/2 weeks): Premolar 3 >***74 days*** (10 and 1/2 weeks): Premolar 4 and Molar 2 >So, the adult teeth typically come in at JUST OVER 7 (SEVEN) WEEKS >of age (or one month and three weeks) through TO ALMOST 11 (ELEVEN) >WEEKS of age (or two months and three weeks). This is well >documented and in veterinary texts (which is what my source is). [Posted in FML issue 4876]
