Ａ．Depending on the individual differences and living environment, the effect of Herb Pack will usually last for 2-4 weeks. The effect will be lost earlier if you keep several pets together or the pet’s body often gets dirty with a walk. You don’t have to worry about the pet’s odor about for 4 weeks if the pet generally stays indoors. In the case of a ferret that has strong body odor, the effect will keep for a week if having only one ferret.
Having several ferrets make the deodorization effect lose faster.
