The Duluth Fire Department responded to a fire at a home in the Lakeside neighborhood Sunday night, its second fire of the day.

Firefighters arrived on the scene at 307 Regent St. around 7:30 p.m. and quickly knocked down the blaze, which was located in the basement and extended to a stairwell, a city of Duluth news release said.

While the homeowners were able to escape without injury before crews arrived, their cat was still in the house. Firefighters rescued the cat from inside and returned it to the homeowners unharmed.

Damage is estimated at a combined $40,000 for the house and its contents. The cause is under investigation by the Duluth Fire Marshal’s Office.

Much earlier Sunday, around 12:15 a.m., crews responded to a fire at a single-story detached garage at 2212 W. Second St., which was quickly extinguished. Firefighters were on the scene for just over an hour.
