Wild animals.

"Mama, come look," he called from the front door. "I see a wild animal."

"A wild animal," I asked. "What kind of animal?"

"A munk," he said.

Sure enough, outside, sitting on our front steps, was a tiny little chipmunk. He sat there for a few minutes looking right back at us and making little chipmunk squeaking noises.

In case you are wondering, my little animals never wear pants.
