I've found that spritzing a bit of bactine on the back of the neck and haunch deters others from latching on and if they have any scrapes from previous scuffles the bactine helps to heal them. A word of caution, bactine initially stings a bit so if you spritz it on an open scratch your little one will jump. Typically when another ferret sniffs or goes to bite, they will shake their head and walk off. If they do bite they let go quickly in my experience. I've been using this for about a year now and have not seen any adverse effects. I did check with our vet before trying it. tle www.ferretfamilyservices.org Kansas [Posted in FML 6234]
