Invisible to deer:

Kill a rabbit:
When you are hunting and see something scurry, hop, or run by, shoot at it. It will 
let out a squeal and die.

Kill a raccoon:
Go by water and walk around until you see a raccoon. Aim and shoot it. Note: You 
cannot claim it.

Killing deer with a bow:
This trick is useful when you playing a season and are required to use a bow to 
hunt a high point deer that keeps running away from you. Get a gun with a scope. 
Aim in front of or at the deer (depending if it is moving or not). Switch to the bow 
and do not move your hunter at all. Aim with your bow and shoot. The same thing 
can be done at the target range.
