Unexpected visitors.

I let my cats come in to the house to hang out for a couple of hours tonight. At about 3am I decide to finally succumb to sleep so I went to let the cats out. When I open the door I hear this deep snarl/bark. Note: I feed the cats on the porch so I thought it was just a dog eating the cat food.
I turn on the light to get a look and I see 3 raccoons! I definitely needed a picture. Unfortunately I left my phone in my room.
I pulled the screen shut and was going to call it good, but for some reason I feel like raccoons can open screen doors. I slowly closed the door, so I wouldn't scare them away, and ran to grab my phone.
They were long gone by the time I got back. Hopefully when I catch them again I'll be prepared.
