If we throw the Norwegians into the black hole instead,
we won't need to endanger any cats.
I concur with this.
As for the idea of using black holes as an energy source as per Romulan Starships, containment had better be extremely reliable if this is going to be done within earth's gravity well.
Loss of containment means the black hole plunges to the center of the earth, maybe bouncing back and forth a few times before settling in the center, at which time earth's gravity will start pushing more and more of the planet into the black hole at the center. This would gradually generate enough heat to melt the crust of the planet into a sea of lava, and eventually the entire planet would end up inside the black hole.
On the other hand, if you want to inspire humanity to hurry up and become a space-faring species as soon as possible, destroying Earth in a slow-but-inevitable manner might be the best way to do that. I believe a guy named Asimov once came up with a similar idea.
