Rengar jungling is fairly basic, the few things that makes him a good choice for jungling is his low level burst damage and his ultimate. If you aren't going to first-blood, playing Rengar passively is also a good choice but passive rengar is mostly comprised with the tanky/damage items as it focus's more on his team-fighting capabilities. When jungling with rengar it's important you keep getting stacks so you can heal yourself.Healing is much more effective then using the q burst as it saves potions which in the long run raises your sustainability in the jungle. When it comes to ganking always ask if they're wards around cause if you get seen its all over. Good places to gank at the top is the top brush cause the river brush is most likely warded and that same goes to bot lane. The only problem about rengar jungle it ganking mid as it is hopeless to gank mid unless you fully undestand rengars abilities. So try to gank mid as soon as you hit 6 and never try to gank mid pre-6 as you have no gap closers and it would just end up wasting your time.

Pros:
+High burst damage
+considerable mobility in the jungle or bushes
+Can target easily in team fights (His Ulti)
+considerable escape mechanics
+Ferocity op

Cons:
-Squishy
-Useless if you don't farm
-Without bushes he's rekt
