One cat was rescued but another was found dead in a house fire on Elliot Street Tuesday afternoon.

Fire crews arrived at the scene to find a single-storey home with smoke coming from the front and left side of the structure, Saskatoon Fire Department said in a news release.

Crews entered the back of the home and found a fire in the basement. One cat was rescued from the home and another cat was found dead. The occupants were not home.

The fire was accidental and caused by a portable heater, the fire department says.

Damages are estimated at $50,000.
