An always-on electric blanket for the cats is being looked at as the source of the fire, Chief Schapelhouman said. There were no injuries, he said. The house is home to three people.
The fire at one point spread to the surface of the front of the home and reached up to the eaves, but never penetrated the interior of the house, he said.
"They knocked it down real quick," the chief said.
The fire caused about $10,000 in damage to the structure and maybe $500 to the contents, he said.
