A 911 caller reported heavy smoke billowing from a home in the Abbott Loop neighborhood Thursday afternoon.

Erich Scheunemann, Anchorage Fire Department deputy chief, says the call came in a few minutes after 2. Just four minutes later, crews arrived on scene to a duplex on Medellin Circle, where they found a "working fire" on the second story. 

It took firefighters about 15 minutes to bring the blaze under control.

AFD Senior Captain Sean Fredenhagen says the fire was contained to an upstairs bedroom, though the upstairs of the unit suffered smoke damage. 

At least one cat perished in the fire, Fredenhagen said. Other cats were able to escape the home. Animal Control responded and is searching for the missing animals. 

Fredenhagen says the home did have working smoke detectors.

"It was nice to see and hear the smoke detectors were working," he said. 

No one was home at the time the fire started. The cause of the fire is not yet known.

The Red Cross responded and is assisting the displaced occupants.
