Common Look-Alikes
Bobcats

- Narrow body
- Light, bouncy gait (not smooth and low)
House Cats

Tracks
Mountain Lion Track
- Large — about 3–5 inches wide (roughly palm-sized)

- Distinct “M”-shaped heel pad with three lobes at the back
- No claw marks (claws are retractable)
Coyote / Dog Track
- Visible claw marks

If you’re able to safely photograph tracks, or place an object like a coin or key nearby for scale, it can greatly improve identification.
Is It Really a Mountain Lion?
Most reported “mountain lion sightings” turn out to be other animals—often large dogs, coyotes, bobcats, or deer seen in low light, at a distance, or for only a moment.
That’s completely normal.
Wildlife can be difficult to identify, and many animals share similar shapes or behaviors—especially at dawn, dusk, or at night.
If you’re unsure, your report still helps. Even reports that turn out not to be mountain lions provide valuable information about wildlife activity in your area.
