I got a second squirrel this morning and this one is a tad more aggressive than the one I got last night. It's making all kinds of odd clicks, hisses and squeals. Some of the sounds remind me of Predator.
I think my squirrel problem might be a little bigger than I anticipated. I placed the caged squirrel in the bathtub while I continued to get ready for work and I heard a loud commotion in the bedroom where two more squirrels are fighting inside the window.
