Deer Invades Home Through The Doggy Door

We're not sure if the deer, doe to be more accurate, knows the people in this video but she sure is comfortable around people things. At first, we see the deer poke her head in through the doggy door of the family's house. Then she pulls back and doesn't do anything for a few moments. Suddenly, she shoves her whole head through the doggy door. Soon after the rest of her squeezes through the door and she disappears into the house through a dark doorway. The people watching this happen don't seem all that concerned though. Maybe she's a pet deer.
