A house in South Redding was mostly destroyed by fire Friday morning. Redding Fire Department was dispatched just after 9AM to Nicolet Lane after neighbors noticed the house was full of smoke. No people were injured as they were not home at the time, but three cats were trapped in the house and perished in the smoke. 80% of the house was destroyed. The cause was determined to be hot fireplace ashes that had been discarded outside the house.
