Fire investigators said an electrical circuit was to blame for a Friday blaze that killed a cat and caused an estimated $400,000 in damage to a Costa Mesa business and its property.
About 5:20 a.m., Costa Mesa firefighters were called to Allison Marine, a boatyard on Newport Boulevard, where a passerby had noticed smoke coming from the building.
At first believed to be a boat fire, emergency personnel who arrived realized the entire building was ablaze and called for assistance.
