SAN FRANCISCO -- A three-alarm fire that burned at two homes in San Francisco's Potrero Hill neighborhood on Christmas Day caused more than $2.6 million in damage and killed two cats, fire officials said today.

The blaze was reported at 6:38 a.m. Thursday at 241 and 243 Mississippi St. and burned for about four hours before being extinguished at 10:39 a.m., according to San Francisco fire officials.

The fire caused the roof to collapse at one of the homes. The structures of the two buildings sustained an estimated $1.15 million in damage and about $210,000 in property was damaged, fire officials said.

No one was injured in the blaze, but two cats were found dead inside one of the homes.
