It took Long Beach firefighters about a half-hour this morning to put out flames in one unit of a strip mall on Fourth Street.

Police officers responding to an alarm and called in firefighters just after 3 a.m. to the strip mall on Fourth Street near Temple Avenue, said Long Beach Fire Department Capt. Jack Crabtree. Flames were out about 3:30 a.m.

Firefighters managed to contain the flames to the unit of origin but heavy smoke got into a veterinary business next door and firefighters removed at least two cats from the smoke and turned them over to animal control officers, Crabtree said.

Arson investigators were summoned to the scene, he said. No injuries were reported.
