AUSTIN, Texas – A fire at an apartment complex in Northwest Austin Sunday afternoon heavily damaged two apartments.

The fire started on the second story of a building at the Polo Club Apartments. Investigators determined the cause of the fire to be improperly discarded smoking material on the balcony. 

No injuries were reported, but 21 people were displaced. The American Red Cross is currently assisting those residents. Thanks to Austin Firefighter Kyle Langhorst, a cat named "Sophia" was reunited with her owner. 

The damage to the building itself is estimated to be $300,000, with an additional $75,000 in damage to belongings inside.
