So can you believe this? I turned on the light and saw an opossum in my laundry basket
What are you going to do with the opossum.
I want to kick its ass to the nearest river
I can see how much of a nuisance this is especially when it was unexpected. You should really call animal control if you find a wild animal in your house. You never know if it will bite or carry diseases and you should be safe.
Why don't I just wait until it leaves?
They may not want to leave, especially if the weather outside is bad. It's going to be faster to call animal control.
