In lvl 1 u start out playing passiv, try to hit the spears, and get all the farm u can, if u didnt kill the biatch yet till ur lvl 6, u use jump and flash (if u need it) to kill the biatch simple, make sure the enemy got under half hp. When u get boots of mobility, this is where you go roaming, you can either run lane to lane farming, or lane to lane hitting spears and ganking, this is why nidalee is a great champ, because of the movement speed in the jungle, what is a tiger with low movemeent speed.

Make sure u practice hitting the spears, or else ur nothing.

Pros
+ Powerful heals with attack speed buff
+ Pro spears
+ Nearly impossible to chase in brush(thats why u need boots of mobility, to piss ur enemies off, and troll the hell out of them)
+ Great damage boost at 6 as cougar
+ Free mini wards (Traps this is where u spam them in the brushes)

Cons
- Being noob
- Cant kill champs till lvl 6.
- Ganks wont work out that well (if not lvl 6)
- Very mana hungry if you waste ur spears.
- No CC
- Needs the right team composition(thats where i like to stand in brushes, make sure you get in cougar if u see the enemy is low)

Position for nidalee is very important, you need to hit the spears on the carrys, or the squishy champs, this is where ur team takes out the squishies, when u see your team needs help, thats where u go in cougar, and "w" in and get the kills.
