Possum. Who would think that, here in NYC, I have a possum problem. This morning, when my husband left for work, we discovered animal droppings on our front steps. Upon checking our front-door camera, I found that there was a possum crawling around our steps around 10:30 last night. So once it warms up a bit, I need to pour some soapy water on the steps to get rid of the waste, and then spray down some pet odor remover & repellent. (We usually use these for stray cats) Any experience or advice on this problem is welcome!
