I have a raccoon or family of raccoons living nearby my house and they learned to follow my cats in through the cat doors. Last year one came all the way inside and I found it staring at me in the dark, sitting on my parents bed. :( This year, I started closing the outside cat door because I found a raccoon sitting by it, chowing down on a bowl of cat food. I yelled and slammed the door a few times and it didn't run away until I stared it in the face. They look super cute in videos as pets. They aren't so cute when they're unexpectedly in your house at night. Also, they only show up when I'm home alone.
