Why do animals fight
The answer to this question goes back to about 6000 years ago.
When God made the world it started off beautiful, and full of love, but the first humans God made were disobedient, so God brought punishment on them which went as far as the whole of Nature.
This is why dogs chase cats, and lions kill zebras, and owls eat mice, and roosters attack each other.
