Ferrets are lively, inquisitive, and comical in their movements. They expend a great deal of energy when they are playing and then sleep deeply for long periods. The life span of the ferret is five to seven years on average in the United States. There have been several cases of ferrets living to be over 10 years of age. Geriatric disease problems usually start at around three years of age.
Many people are concerned about the odor of the ferret.
Therefore, removing the anal glands is an unnecessary procedure in ferrets and in fact does nothing to remove body odor. Males are normally twice the body size of females. Ferrets reach their adult weight by six months of age. As would be expected, weight is put on during the fall and lost in the spring. There is also a hair loss that occurs at these same times.
