Bear scare

Last July my wife and having dinner when two of our cats came storming in the house via the cat door from the outside screened in patio and ran upstairs, then we heard another one of our cats, Pembroke, hissing up a storm. We ran downstairs and as we did through the window we saw a 300 pound black bear on the outside of the screening facing Pembroke. She was just stood there, puffed up and with her hissing it looked like she was challenging the bear. As soon as we opened the door from the house the bear took off running. A few weeks later a bear broke through the screening to get at a bag of bird food we had mistakingly left on the patio.
