1st they need there ditemper every year here i think in england idk about where you are and make sure they have rabies

2nd for treats the best thing you can give them is: raw rabbit, raw chicken wings, raw pigeon (feathers and all) not coked as this causes blockages and ya dont want that! also there is ferrettone or ferretvite


3rd ferret nail clipper? my guess is that they are crap i just use a pair for cats and dogs


(P.S joining this forum www.forum.ferret.com would give ya great help on al your questions!)
