What's the difference between these species?

Do you know how long it will take to explain to you all of that? Google them and learn for your self. If you want you can just look at pics to see that they are different, but if you want a break down of there genitic and behaverial differences you need to do your own reasearch. The easist answer is that they are all different animals, almost everything about them is different. If you can't look at a lion and a cat and tell the difference then no amount of explaining is going to help you. Happy reasearch.
