I wish I could remember where I read this, but in Texas in the 1890s, they actually but different animals in arenas, like bull fighting to see which animal would win. The biggest problem they had was getting these animals to fight as thier scents were so foreign to each other that they would run to the opposite sides of the arena.
And animals fight only if they are threatened or thier young are threatened, especially when they know nothing about thier potential opponent.
Those animals showed more sense than the so called superior species who often are the real animals.
I do know that theres nothing as dangerous as a mother animal defending her young, I saw footage once of a feral Cat beating a Grizzly Bear away from her Kittens in Yellowstone Park by faking his noses.
Help me BOO BOO!!!
