As far as I know, it is illegal to hunt with ferrets in the United States. I think parts of England still allow it. You might google your particular area just to make sure.
Awwww! Cuties!
I've had ferrets for about 16 years now. At one point I had 5 of them rampaging around. I have two right now (Jake and Claudius).
Congrats on your new babies! It's amazing how much fun it is to have a big pile of them zooming about!
