We have a happy little family of chipmunks too. They live under the back step.

I have a cement basement and all our wires are off the ground, so no fear of him/her damaging them.

We had a ground hog a couple years ago. Allen tried to chase it down ..... you should have seen waddling cat following waddling hog. I have no idea what happened to ground hog #1. It just stopped living in our yard.
