GLENDALE (CBSLA.com) — Firefighters saved a cat who was stuck in a burning apartment complex in Glendale Monday morning.

The fire broke out just after 10:15 a.m. at the Fort Dearborn House Apartments in the 400 block of West Doran Street.

The blaze was primarily in the second story unit but flames also spread to the third floor where officials were able to contain it.

“The fire was so intense it quickly spread up to the unit above,” Glendale Fire Department Battalion Chief Vince Rifino said. “The flame lengths were well in excess of 12 to 15 feet, which lapped over the side of the building.”

Firefighters pulled the unconscious cat from the second story apartment.

“The cat appeared to me to be lifeless, unresponsive,” Rifino said. Officials used an oxygen mask to revive it.

No other injuries were reported.
