The latest cub was found holding on to a tree in San Anselmo near Carmel Way early Saturday morning.
Jennifer Brinn-Barbee says she contacted WildCare in San Rafael after she found the bobcat kitten crying in a tree outside her house.
WildCare picked up the little cub. Officials believe the male bobcat is related to a female cub found by a neighbor a few weeks ago.
WildCare shared video on its Facebook page, showing the female cub being fed on August 8, shortly after she was rescued.
"This 3-week-old kitten was found during ivy removal in a yard in San Anselmo, no den or mom in sight. Med Staff worked with the homeowners and attempted to reunite multiple times but unfortunately mom never returned," said WildCare in a Facebook post.
No word yet on what happened to their mom.
Officials say the little brother and sister will be cared for at the Wildlife Center of Silicon Valley. They hope to release them back in the wild once they get a little older.
