Yep, 50 is next to nothing, and it will be really difficult to take care of them in such low numbers.

Cheetah ran really fast. it can run 3 times faster than great Usain Bolt (Fastest runner of the planet). I read some where it Cheetah can't run at the fastest pace of 112 Km/hr for more than 15 seconds. I am not sure about the authenticity of the writer. Thanks for sharing @valth

Yeah, it's extremely fast. And no, they can only run for the max speed for a very short time, and they often are unable to catch their prey during this time as well, so it's not even like they are some "superhunters" because of their speed.
