Ferret Has Pimples On Stomach

About a week ago I noticed little what looks like pimples on his stomach. Since then they did not get bigger, could this be allergies or should I be worried?

Small, reddish pimple-looking marks on your ferret’s skin are most likely to be reactions to flea-bites. That is to say, your ferret probably has fleas. Be aware that if you have any other pets in your house they will almost definitely have become affected too.
Luckily, there are many flea treatment products on the market which are either designed specifically for ferrets or are safe to use on ferrets. See our related resources below for further information.
