I love the big cats, especially tigers. But I also love lions, cougars, cheetahs, and lynx.
My all-time favorite is the American Bison. Not many in the wild today. Most now are on ranches, preserves, and state parks. But make no mistake, they are very wild. Every year people get killed or seriously injured trying to pet or photograph the "fluffy cows". If you ever encounter one, watch its tail and keep your distance. If they are annoyed with you, you are too close, or between them and their baby, they will raise their tail as a warning. That means MOVE NOW.
