What I'm finding out is that ferret breeders are few and far between. Apparently, they're a really difficult animal to breed, so there's not a whole lot of them around.
I found a breeder with shipping experience across the country. I think we will be buying from her, then paying to have our fert kits shipped to us.
I didn't want to buy from a petstore, either. I have no problem with rescues, except that I would rather not deal with a whole bunch of health problems right off the bat. I have 2 rescue birds, one petshop bird, a petshop ig... this time, I wanted to try buying from a reputable breeder.
