Ferrets usually lose fur twice a year when they shed - in spring and in the fall. This is very normal. I recommend you treat the ferret to a laxative for cats or ferrets twice a week, more often if the little fellow in coughing or his stools look thin. Change bedding two to three times a week to prevent them from licking up excess fur during shedding season as well. Fur ball medication can be given to the ferret weekly as a treat during the rest of the year.
Ferrets also lose weight in the Spring - sometimes almost twenty percent of their body weight.
As long as he is active, eating , drinking and pooping normally, this is a natural part of a ferret's life cycle. Keeping multiple animal types in the same household can be difficult if not tragic.
