An elderly Indiana woman hosted some unwanted guests in her home Tuesday night — three deer.

The wild animals busted through a bedroom window of her Decatur retirement home, knocking her over and leaving her trapped on a living room couch.

The senior citizen managed to call the cops, who shielded the woman and subdued the deer.

One of the animals was in the living room with the woman, while two others were in the bathroom.

The woman wasn’t injured — and “was amazingly calm” during the break-in that left her apartment in disarray, according to Sgt. Kevin Gerber.
