Was doing my normal training hill climb up to the tower (Bernardo peak) after work solo. About 3 mins into it from the lower fire road, went up a small step up and there it was about 20ft in front of me was knee height cat on the trail, almond color fur and long black tail. Looked to be about 40ish lbs(bit smaller then my boxer). I unclipped, it looked at me, then it turned around and headed up the trail. Paws were huge!! I waited for it to get a bit farther up before I 180* and booked it down hill, didn't know if it's mommy was up the trail.
Be careful out there!!
