In my opinion, I think hunting would add an entirely new dimension to roleplaying, especially for people like me who like the realistic side of things. Say, if you actually HAD to provide food for your pride/pack. You could store food in cashes, and stray players could act as scavengers that could attempt to steal from your cashes.
I think the best way to implement it would be having different settings to the game. As in Free Play, wherein you don't have to worry about a health bar, stamina, hunger, or anything like that, Survival where you would be forced to eat and drink to survive, and PvP wherein you could physically attack other charachters outside of RP.
So say, if you were running a very realistic rp map, you could set it as PvP and Survival together, so that fights could break out among the pride members and food would have to be hunted for and brought back to the dens, or if you were doing a more whimsical or story based rp you could set it to Free Play so you don't have to worry about such things.
