Ginny Ballou said the raccoon entered her house Wednesday through a back porch pet door.
"I was asleep and something jumped on my face. At first I thought it was my cat, but then it bit my chin and lip, and latched on," she told WBZ-TV, Boston, Friday. "It was clamped on me, and ripping my face. I finally got him off and hit him with my phone."
After she called police, a state environmental police officer arrived and captured the raccoon, which was found to have rabies and was euthanized. Ballou was treated at a hospital and has begun a series of anti-rabies shots, WBZ-TV said.
