A young mountain lion prompted a police response in San Francisco’s Outer Sunset neighborhood on Friday, September 18, 2026, before wildlife officers successfully tranquilized and captured the animal near 44th Avenue and Ulloa Street.
Urban wildlife sightings in the Bay Area rarely unfold with the urgency of a morning gridlock, but residents near the western edge of San Francisco found themselves in a temporary standoff zone after a big cat navigated front yards just blocks from the Pacific Ocean. The incident drew a multi-agency response, pulling in local law enforcement, animal control specialists, and state wildlife game wardens.
Morning Chaos and Neighborhood Standoff at 44th and Ulloa
The alert sparked around 7:30 a.m. local time when dispatchers received reports of a mountain lion prowling the Sunset District. Video footage shared across social media captured the adolescent cat wandering behind residential bushes and beneath slightly open windows in the area surrounding 44th Avenue and Ulloa Street.
As municipal workers flooded the grid, residents were told to stay in their homes.
The cat darted away as animal control officers first attempted to administer a tranquilizer, leading to a brief chase that pushed media and bystanders back. The animal ultimately slipped into a patch of dense brush near the corner, prompting a standoff before state and city crews successfully administered the sedative.
Coordinated Multi-Agency Capture and Public Safety Response
By late morning, the operation shifted from containment to rescue. Animal Care and Control spokesperson Deb Campbell confirmed that city and state agencies—including the San Francisco Police Department, Animal Care and Control, and the California Department of Fish and Wildlife—collaborated on the response.
Mayor Daniel Lurie utilized social media and video updates to keep residents informed as the situation developed near 44th Avenue and Vicente and Ulloa streets. The animal was safely tranquilized, and state game wardens immediately took the cat into their care.
An official Nixle alert issued shortly after the operation concluded reassured the community: The incident has been resolved, there is no danger to the public.
Urban Encounters Across the Bay Area
While San Francisco’s steep hills and urban density do not align with typical mountain lion habitats, the southern border of the city sits roughly five miles north of the Santa Cruz Mountains, a region supporting a localized population estimated by experts at around 50 to 60 big cats. Occasional wanderers bridge that gap, utilizing coastal stretches to enter populated zones.
Friday’s event follows another mountain lion appearance in San Francisco earlier in the month. A predator was spotted hiding in a tree near Fell and Baker streets in the city’s Panhandle neighborhood near Golden Gate Park. Wildlife officials have not determined whether Friday’s adolescent cat and the earlier Panhandle sighting involved the same animal.
Official Wildlife Guidance for Urban Residents
In response to urban sightings, local authorities reiterated safety protocols for residents encountering predators in residential corridors. Officials stressed that anyone who spots a mountain lion should maintain distance rather than panic.
- Slowly back away and never run, as running can trigger a chase instinct.
- Keep children close by picking them up, and ensure dogs remain secured on a leash.
- If the animal approaches, make yourself appear as large as possible by waving arms, shouting, and throwing objects if necessary.
Residents who spot wildlife in residential sectors are urged to contact San Francisco Animal Care and Control directly or dial 911 for life-threatening emergencies.
