Orphaned Mountain Lion Cubs Released in San Diego County After Months of Rehab

Tracking collars will allow biologists to monitor how the young cats adjust to life back in the wild.

Overview

  • Two male cubs were released on Sept. 18 onto public land north of Ramona after roughly six months of care, each weighing about 60 pounds.
  • The pair was found malnourished near Poway in March and was trapped by UC Davis’s California Carnivores Program with state wildlife officials before transfer on March 26.
  • Rehabilitation emphasized minimal human contact and survival training, including exposure to deer meat, feeding of live small prey, and use of visual barriers and camouflage.
  • Before release, the lions were microchipped, tagged, and fitted with tracking collars to enable post-release monitoring and reduce human-wildlife conflict.
  • San Diego Humane Society’s Ramona Wildlife Center has treated 16 mountain lions since 2020 as conservation groups report lower statewide populations and ongoing threats from vehicles, habitat loss, and wildfires.
