I'm sure a dozen people will respond to this. :) The kind of staggering you're describing is indicative of mold hind end weakness, which can be caused by a lot of different things. Given the age of your ferret and the behavior you describe, I would lean toward a blood sugar problem, but there are other possibilities. If you have any karo syrup on hand, try giving her a lick or two, or rub it on her gums. Molasses or maple syrup will also work. If her glucose levels are low, she should recover rapidly. Even if the problem is something else, the sugar will probably give her a burst of energy. Also check to see if she's dehydrated. Extreme dehydration can also lead to hind end weakness. If her scruff doesn't snap back into place after you pinch it, try encouraging her to take some pedialyte. If she won't drink it, use a syringe and slowly squirt it into her mouth, sideways. Don't squirt it straight down her throat. :) If this is insulinoma,the good news is that it's very treatable, with surgery if your fert is a good surgical candidate, and if she's not, a good diet and exercise regimen can probably keep her happy and healthy for years. Definitely get to a vet as soon as possible, of course. I'm sure you've been there by now, but since you're an anonymous poster I had to send this to the list. Let us know how she's doing!
