It's the second straight weekend where a vacant home in Quincy caught fire early in the morning.
Witnesses around the scene on Saturday woke up to the flames. One witness told WGEM News their pet saved their lives.
It was around 5:30 Saturday morning when fire crews were called to a multi-story brick home fully engulfed in flames.
"The house across the street was engulfed in flames when I walked out the door," neighbor Tracie Henry said.
Henry walked outside and immediately took a video. She said her husband woke her up and she couldn't believe it.
Nancy Huston lives in the apartment next door to the fire and says she able to get out safe, thanks to her cat.
"My cat woke up my Uncle Jim," Huston said. "He came in there and said, 'Nancy wake up. I said what for?' He says the house next door is on fire."
Quincy Fire Officials say they're unsure how the fire started. But, when they arrived on scene Assistant Fire Chief Bernard Vahlkamp says they decided to battle the fire from the outside, instead of going in.
"The roof collapsed approximately 10 minutes into the fire fight," Vahlkamp said. "Like I said, they made the decision to protect the exposures right away, until they could get some water inside. But, the roof came down almost immediately after they arrived on scene."
