Hamilton Fire crews rescued a 35-year-old man from a second-floor window during a multiple-alarm fire on the corner of Queen Street South and Hunter Street West around 1 a.m. Monday.

Three cats died in the fire, said Claudio Mostacci, spokesman for the Hamilton Fire Department.

When firefighters arrived, they found smoke and flames coming from the second floor of the home, the south unit of a three-unit rowhome strip. The unit was rented as a duplex and the Red Cross is helping the tenants on the ground floor find alternative living arrangements. 

Estimated damages to the house are $250,000. The cause has not been determined. The Ontario Fire Marshal has been called to help in the investigation. 

Paramedics took the man to Hamilton General Hospital for smoke inhalation treatment.

Police closed Queen St. from Jackson to Bold streets.

Firefighters were able to extinguish the fire without it spreading to the adjacent units, Hamilton Fire said.
