This message is in response to the young man in Arizona keeping his ferrets outside. I live in Tucson, and would never dream of letting any of my 13 ferrets outside, even for a brief period. Yes, it's a dry heat, most of the time, but it will definitely still be too hot for your babies in the day during the summer, and too cold at night during the winter. You did not mention how you have them housed. Are they completely protected from predators? I routinely have hawks hunting doves and rabbits in my backyard, not to mention coyotes, javelinas, bobcats, and various species of snakes that periodically visit. Please consider these factors and think of what is best for your ferrets.
