If you were going to look for a safe flea product for your ferret, what would you choose? I am looking into this right now as more of a preventative measure than anything else. My ferret Casey does sometimes go outside for walks when we have decent weather and there are usually neighbor's cats there too. Casey is a 4 year old male sable, in good health. Let me repeat that I do not feel he has fleas at this time. At his next veterinary visit I will also bring this up and see what his recommendation is. Thanks for any assistance.
