The bottleneck event that the cheetah went through in the last ice age ultimately resulted in a stronger, more robust species.

It is true that Cheetah went through a bottleneck in the last ice age, but it is not true that it resulted in a stronger species - so the entire statement is false.
Bottlenecks are generally bad for species as they reduce the species' genetic variation which is typically bad - it makes them less adapted to new circumstances
