Hi all! I have never had a flea in my house... ever. I know that I'm lucky. After 7 1/2 years with a dog and 4 years with ferrets, I found 5 fleas on Mandy after she came in from a walk. I am now concerned that the girls will get these fleas (although we have bathed Mandy 4 times and applied Flea Control). I want to know if K9 Advantix or Advantage or Frontline can be used on ferrets? Any help is MUCH appreciated! Thanks y'all! ~Michele, Slave to Fattie, Pearl, and Onyx (the spokesferret), and their loving guard dog, Mandy. [Posted in FML 5975]
