“We can’t say it enough: Wild animals are not pets,” said Frank McGee, CPW’s area wildlife manager for the Pikes Peak region.
According to officials, the attack happened Friday morning, when the neighbor was out walking her dog.
The neighbor said she was "surprised to notice" the deer following her before it attacked, knocking her down and "trashing her with its antlers."
The attack went on for several minutes as the victim tried to run to a neighbor's house, and then to her own home.
"Repeatedly the deer knocked her down and gored her," CPW said. "The deer even continued to attack as she frantically opened her garage door."
The attack finally came to an end when the woman ran between two cars in her garage.
The victim suffered serious cuts to her head, cheek and legs. She was also bruised and hospitalized overnight.
A wildlife officer who responded to the scene discovered the deer with "fresh blood covering its antlers" that "aggressively" approached the officer, according to the agency.
The officer euthanized the deer and took it to CPW’s animal health lab in Fort Collins to test it for rabies and other diseases.
"The deer’s stomach contents confirm it was being fed by humans as it contained out-of-season foods including hay, grain, corn and possibly potato," the agency said.
Housley was cited with illegal possession of wildlife and illegally feeding wildlife, both misdemeanors. She was also issued a warning for possessing live wildlife without a license after she described keeping the buck in her home, her garage, and on her property, according to CPW.
The two misdemeanors carry fines and surcharges totaling $1,098.50, CPW said.
“Feeding deer habituates them to humans. They lose their fear of humans and that leads to these outcomes that are tragic for both wildlife and people," McGee said in a statement. "Injured and orphaned wildlife should be taken to licensed wildlife rehabilitators.”
