Bobcat vs Mountain Lion
Wild cat in the yard - how big a deal is it?
The quick tell
The tail answers instantly. A bobcat carries a stubby 4-7 inch "bob"; a mountain lion drags a thick, rope-like tail nearly as long as its body, tipped in black. Size confirms: a bobcat is roughly twice a house cat; a mountain lion is a 6-8 foot, 80-180 lb predator.

I saw a big cat with a long tail in the East - was it a mountain lion?
Outside Florida’s panther population, breeding mountain lions are essentially absent from the East, and most reports resolve to bobcats, large housecats, or dogs. But young males do wander a thousand-plus miles from the Plains, so a clear photo with that long black-tipped tail is worth reporting to your state wildlife agency.
Is a bobcat a threat to my kids or pets?
Bobcats view people, including small ones, as trouble to avoid - attacks are vanishingly rare and usually rabid animals. Very small pets left out at night are the only realistic concern. Seeing one is a privilege, not an emergency.
