Wild animals in the woods - NOT realistic.
Grizzlies - Add 1000 hp and bleed attack. Add mortal wound too

Panthers and other wild cats - Raise their dex by 100 and add bleed attack.
Snakes - For god sakes... Add 200 dex & poison! Really? And why can't we step over small snakes??
Gorillas - Add a projectile... Poop (just a random thought)
Brown Bears - They tend to rip your face off
Wolves - Pack instinct, gang up on you and eat you
Wild Boars - add 500 hp, 98 each resist and mortal wound
Alligators - Special attack to match their real life attack
Add stuff like this to benign animals that are realistically dangerous in the wild. You cannot just walk up to a wild cat and tame it. Try walking up to a wild grizzly irl and tame it... Let me know what happens. Walk up to a savage ridgeback ... well... nm I dunno what those are but still. Get the point?
