All of mine were unfortunately from MF, but at the time of purchase I knew nothing about ferret mills or puppy mills or the poor breeding practices at MF. MF is also a puppy mill. They breed Beagles to be used exclusively in laboratories because of their trusting, docile temperaments. They breed ferrets until they can't produce anymore and they use special lighting to trick the jennies into estrous as often as possible. Let's not forget the extremely early age they spay/neuter their kits. When I bought one of my ferrets from Petco, he was the only one left and he was crying. They said they were having to bottle feed him, but that he was 8 weeks old. Uh, I don't think so, more like 4-5 weeks old. We still had to give him formula when we got him and that included 3am feedings. I will never make the mistake of buying a ferret again, they will be strictly from rescue. I did find out that there is a local "rescue" group that has a ferret. The unfortunate thing about it is, this group is run by the trashiest folk there is and the care for their animals is substandard. I don't want to give them my money, but I don't want to see this little weasel stuck with them or adopted to some loser.
