To those of you who mentioned they weren't seeing results with PROGRAM, the new flea pill, you won't see any for a while. The pill does not, I repeat- Does Not, kill adult fleas. Its purpose is to sterilize the eggs that the flea lays, therefore its like a birth control pill for fleas. When the adult flea bites an animal on PROGRAM its eggs become sterile and do not hatch. The adult flea can still live a long time on the animal, as long as 6 months according to some sources. I work for a vet, and we advise any PROGRAM user that while the pill is effective in stopping flea production, they still need to treat the animal and their home for fleas if they currently have a problem with fleas. If not, they should still keep a spray or flea shampoo on hand that they have gotten from their vet, as most over the counter flea products in pet stores are uneffective in flea treatment. So if your ferret is on the pill, don't think it can or will stop them from getting fleas, they can but they just won't be able to reproduce. Remember even you can bring fleas into your home, via your shoes etc. PROGRAM is or at least seems to be effective in stopping flea production but you also need to kill the adults with something else. Hope this helps those of you wondering why this "miracle pill" doesn't seem to be working. The results won't be noticable until you get rid of the adults. Happy ferreting!
