Re: Ferretone, Companions choice online has some £10 per 500ml bottle. I got some the other week it has been hard to find over the past year. We use codliver oil capsules and liquid it's brill for when you need them to be still...Like ears and nails...lol Pets at home also have ferret paste which my guys luv as well. We had a biter and used a time out box (ferret jail) everytime he bit he went into the box and had to watch his mates havin' fun it took about 2 weeks, may not work for you but did for us. Good luck
