Hey Kristen, When I d my ferret Julia, she also had fleas. I got rid of them last January, and they haven't come back. What I did was give her a bath in cat flea shampoo every other week and I sprayed out on the patio and around her cage. Also, I changed her bedding VERY often, and cleaned out her house so there weren't any eggs around. ALSO, I gave her baths in baby shampoo between her flea shampoos to kill juvenile fleas. The trick with fleas is to realize that eggs aren't easily destroyed. Therefore, you must give baths OFTEN to kill fleas on the ferret, and use SOMETHING to get rid of the fleas around the house. I used a FLEA FOGGER on my house in conjunction with frequent baths. By the way, I use (this may sound strange, but it works) paper towels for Julia's bedding. This works well, because she can tear them up, then I can change them when they get smelly or dirty. I fold about 10-15 towels up into a thick mat and put that into the box in her cage. This way I have a disposable bedding. This was especially helpful in getting rid of fleas, because I could change it OFTEN. Since I live in a warm climate, Southern CA., this may not work for everyone. D.E. Brea, CA [Posted in FML issue 1007]
