The behavior of the ferret is affected in some way by his being male or female.
In our experience as breeders and owners of ferrets, we find that females tend to be more active and curious than males, especially the first year of age. Adolescent males (until 1 year) are just as lively as the females, but they tend to calm down as they get older. Another observation is that males are more surprised and frightened by what they have never seen or heard before, especially new or animal noises. Le femmine, on the other hand, jump to right and left in search of something new to discover.
Our first two ferrets, Bonnie e Clyde (yes, we called them as the two thugs who robbed banks and terrorized the United States in 1930), were 6 weeks when we bought them, Christmas Eve of 1993, and reflected their names. Crescendo, Bonnie's personality has not changed has been very active and persistent in getting into trouble, instead Clyde developed a personality quieter. Play with a lot of enthusiasm, but in a short period of time loses interest. We always joked that if they were to do a robbery, Bonnie would be the one who does the bank heist and Clyde would be out, asleep at the wheel of the getaway car.
