I actually use superglue for this, but yes. (Superglue is fragile enough if I ever really needed to turn it off I could whack it.) We don't have cats, but we have feet and a mess of adapters under the table.

Other nice thing about laptops: "The power went out! Oh no! Oh, wait. I can still work. And hey, the neighbors have power -- I still can find a wireless network!" :)
