Crews on Wednesday extinguished a five-alarm brush fire near the intersection of Highway 29 and Highway 37 in Vallejo.
The blaze, which was reported about 3:40 p.m., charred about 10 acres and was contained to brush. Vallejo Fire Department spokesman Bill Tweedy said no evacuations were ordered.
Two engine companies providing structure protection at nearby homes in case wind caused the fire to spread. Light to moderate winds were blowing in the area, which fueled the fire and made it difficult to contain.
Firefighters searched a homeless encampment, where the fire appears to have started. During the search crews were able to rescue a kitten from the flames.
The California Highway Patrol said the blaze did not impact Highway 37 and only one lane on southbound Highway 29 was affected.
Assistance was called from surrounding areas, including Crockett, American Canyon and Solano County. A Cal Fire helicopter was also seen making drops on the fire.
