Firefighters pulled a pair of wet and frightened cats from the smouldering remains of a home in northwest Calgary on Christmas.

The blaze at the home on Bow Crescent N.W. began about 10 p.m., fire officials said in a news release.

When firefighters arrived they were met by the home's four residents, who told them the cats had not made it out of the house. Two of the residents were transported to hospital by EMS as a precaution.

Because of the possibility of the fire "rolling over the crew, the firefighters used several different tactics to deal with the heavy volumes of smoke, heat and flames, the release said.

Once the blaze had been extinguished, the firefighters found the cats and returned them to their owners.

While the interior of the home suffered severe damage no adjacent structures were affected.

The cause of the fire is under investigation.
