This is basically to Melissa, but I thought I'd post it here since at least one other person said her ferret had similar symptoms. This might be really obvious, and since I've just come back I don't know how long Noodle's been lethargic and snuffly, but do you have air conditioning on? I'm finding that Amelia gets snuffly and sneezey and sleeps a lot after a couple of days of non-stop AC. It doesn't seem to affect Cully as much. If you do have AC on, and it's cool enough at night to stand it, you could try taking a break from it. I'm probably way off the mark here, but it was just a thought. I hope Noodle's doing ok-- Regina, Cully, and Amelia the sneazel [Posted in FML issue 1985]
