How about when you're in trouble and you need some animal to save you? lets say, dogs or some other random creature? you equip you're animal bait, throw it on the ground and boom. There you go, you're saved by a summoned deathclaw, that allows you to escape! :disguise:

Just use a stealth boy

How do you use a stealthboy, when you're already spotted?

Animal Friend, level 2.

Animal bait would just /attract/ animals. Why would it make them side with you? Especially something like a Deathclaw? That's like saying if you offer a steak to a violent dog, it'll become your best friend. Or even better, if you offered some fish to a Grizzly. More than likely it'd swipe your head off, and have a meal of both the bait and you and be set on food for the day.
