As if chickens didn't have enough predators

Exotic cat

Everybody likes chicken, including some who don't even belong here. One of our customers who lives near New Glarus found this cat in her chicken coop. It killed 4 of her chickens and scared the hell out of her. She thought it was a bobcat because it was BIG! But, apparently it belongs to a neighbor and got outside accidentally. The neighbor eventually captured it. So, we're wondering what it is? Some kind of African crossbreed?
