Hi dear lol-players!
This is my first guide, and so feel free to give me hints and tipps.
But also, keep in mind that this build is still under construction.

Why should u play Cho'Gath as a jungler? Why should you use one of the most powerfull top laners, as a wolf hunter? In the following guide i will give you some reasons why.
First off all i would like to mention, that Cho'Gath's passive Carnivore will help u to jungle much longer in the first jungle phase. Usually you can hold the same level as ur laners.
Secoundly, your skill Rupture has nearly the same effekt like Amumu's Bandage Toss. You may stun a target from distance. Ofcourse Bandage Toss would port you to ur target, but it only afects one opponent. Rupture can knock up more enemies at the same moment, additionaly there is is a slow - effect on your target.
Also Cho'Gath has the ability to silience champions with Feral Scream. This denies a lot of champs from using skills, with means that they will do less Damage and prevent them from escaping.
Next thing on our pro-side why Cho'Gath should be played as a jungler, are Vorpal Spikes.
This passiv will help you in the jungle by dealing splatter damage.
My last point would be Cho'Gath's powerfull ulti. Feast deals a lot of damage and also will gain you health per stack. Also u get bigger, what dont even looks nice, but also the opponent Team will handle you in a different way. Yust the apperence of a 6 - stack Cho'Gath may push them back.
