An investigation is underway following an early morning house fire that leaves a cat dead.

The Knoxville Fire Department was called to the 1300 block of West 4th Avenue and found heavy smoke and flames coming from the rear of a home. Crews were met by a man who said the bedroom of the house was on fire and that everyone was out of the home.

Crews quickly put the fire out but the home has suffered heavy smoke, water, and fire damage to the rear of the home.

The American Red Cross is assisting the occupant.
