A fast-moving fire destroyed a house in Springvale on Friday morning, killing a cat and forcing the residents to flee.

“They literally ran out without shoes on,” said Sanford Fire Capt. Gary Cushing.

The cause of the fire, which started in a first-floor bedroom, had not been determined, but appeared accidental, he said Friday afternoon.

Three of four people living at the 21 Witham St. house, which they rented, were inside when the fire started, he said. The other resident had left for work.

None of them was injured in the fire, Cushing said. A firefighter was treated at the scene, but Cushing wouldn’t say what the medical emergency was.

Firefighters from Sanford, Acton, Alfred, Wells, Lebanon and Kennebunk responded, as well as rescue workers from several towns.

The fire was under control by 8:21 a.m. and out by 9:48 a.m., Cushing said.

He said the 2 1/2-story house, valued at $95,000, was total loss, as were its contents, which he estimated were worth about $30,000.

Cushing said there was minor damage to the vinyl siding of a neighboring home.

He said all the residents have found places to stay.
