A mountain lion wandered through San Francisco’s Outer Sunset neighborhood, forcing police and wildlife officers into a tense, hours-long chase before the animal was safely captured.

Story Snapshot

A mountain lion was spotted near 44th Avenue and Ulloa Street in San Francisco’s Outer Sunset on September 18, 2026.
City officials issued a public alert and sent Animal Care and Control, San Francisco police, and state wildlife officers to the scene.
The lion was tranquilized, captured, and placed under the care of California Department of Fish and Wildlife game wardens.
This marks the second high-profile mountain lion sighting in the city in recent months, following an earlier incident in the Panhandle.

What Happened In The Outer Sunset

City officials and local news outlets reported the sighting near 44th Avenue and Ulloa Street on September 18, 2026. The San Francisco Department of Emergency Management sent out an alert warning residents in the area. Animal control officers responded quickly after receiving multiple reports of the big cat nearby, according to SFGATE. Police helped set up a perimeter as the search unfolded across the quiet residential blocks.

Officials told residents exactly what to do if they came face to face with the animal. Patch reported the guidance was simple: back away slowly, and never run. Running can trigger a predator’s chase instinct. Residents were told to call Animal Care and Control for non-emergencies, or 911 if their safety was in immediate danger. The advice matches standard wildlife safety protocols used across California.

Capture, Care, And Release Back Into The Wild

After a tense standoff, wildlife officers tranquilized the mountain lion. KTVU and Patch both confirmed the animal was captured and then handed over to California Department of Fish and Wildlife game wardens for evaluation. The San Francisco Zoo also took part in the multi-agency response, according to reporting that named the agencies involved. The lion was later released back into wild habitat, following the standard practice for healthy, uninjured animals found in urban areas.

Reports describe the animal as spotted, roaming, or prowling through the neighborhood rather than confirming it ran through multiple streets. Most accounts place the actual encounter at a single intersection, not a citywide chase. That distinction matters. A dispersing young mountain lion moving cautiously through a quiet residential block is a very different scene than one sprinting down Market Street, even though both make for dramatic headlines.

Why This Keeps Happening In The Bay Area

This was not San Francisco’s first mountain lion scare this year. Just months earlier, a mountain lion was confirmed in a tree near Fell and Baker Streets in the city’s Panhandle neighborhood, prompting a similar response from wildlife authorities. Wildlife experts say young male mountain lions often wander into unfamiliar territory while searching for new hunting grounds after leaving their mothers. The Bay Area’s mix of parks, freeways, and dense neighborhoods creates unusual paths for these animals.

Conservation researchers note that dispersing mountain lions rarely intend to enter cities at all. Fragmented habitat, cut off by highways and development, sometimes leaves young cats with few natural corridors to follow. Most eventually turn back toward rural land on their own, without needing capture. San Francisco’s Animal Care and Control receives multiple mountain lion reports most years, though the vast majority never require tranquilizing or relocation.

The Outer Sunset incident ended the way wildlife officials hope every one of these encounters ends: no injuries to people, no harm to the animal, and a safe return to the wild. That outcome reflects real coordination between city police, animal control, and state wildlife officers working together under pressure. For residents, the sighting was a reminder that California’s wild edges are closer to home than many assume, even in a dense city like San Francisco.
