A 40lb bobcat is a real toad Dave, I guess the one in the pic to be somewhere near that, they have pretty good hair making them took bigger.

If indeed the cat you saw was 60 - 80 lbs it must have been a young mountain lion.

Most of our Cali cats are about 20lbs with the occasional 30 -35 lber being exceptional.
The big tom that my kid missed was in Northern California's Modoc county near the town of Alturas last winter when we were hunting coyotes.
It came in to a distressed rabbit call, it was a huge tom that I guessed at 35+.
The kid shot right over him at 127 yards.
He was crushed.
