The State Fire Marshal's Office is investigating the cause of an overnight house fire in Yarmouth that injured two people.
The blaze broke out at a home on Astor Way around 2:00 Thursday morning but crews were able to quickly knock down the flames.
One of the victims was a woman who suffered critical injuries and had to undergo CPR on the front lawn before being rushed to a hospital in Boston.
The other victim was a girl who escaped on her own and was taken to Cape Cod Hospital to be evaluated.
The family cat died in the fire.
