Look on the output plug -- along the side of that there is often a marking.

It's driving me crazy!)Try soaking some cayene pepper in water overnight, then liberally applying the substance to things you would rather your cat not eat. It could be a lifesaver for your cat, if it keeps her from chewing into a 120 volt cord. And maybe an alternative toy -- maybe something with catnip.
