Splicing it back together shouldn't be a problem. Make sure everything is isolated and insulated well with electrical tape after you strip off the sheathing and twist the severed ends...back to together as they were before sharpening your cats teeth.
As far as danger goes...I can't see any danger what so ever if the thing isn't plugged into the wall. This thing probably has a capacitor in it, which can store an electric charge, but leaving it sit for 24 hours should discharge any stored electricity.
I would try this without thinking twice, is what I'm trying to say. Even if I could afford the 70 bucks for a new one.
I'm not an electrician nor a electronics engineer...but still...8.4 volts at 1amp is nothing.
