not an animal!!!
it's a really fast car that was in GTA 1-5. I have all of them and they are all awesome (except for 1,2, and London) and also, in GTA San Andreas, you can mod out the cheetah... just to let you know (buy the game now!!! on ebay or something)
Person 1:Whoa, did you see that Cheetah!?!?!
Person 2:That's not a Cheetah, it's a Perrenial, noob.
