"It has gone over the edge," Lee Palmer told dispatchers. "He's trying to attack us—he's very hostile. He's at our door; he's charging us."
The 4-year-old male cat, named Lux, had first scratched owner Teresa Barker's 7-month-old son on the forehead after the baby pulled the animal's tail.
Barker's boyfriend Palmer then kicked the cat away from the baby, setting the animal off, KATU reports.
