How can I help animals, any advice or info please answer.?

Alright, so I really want to help with animals and all, but I don't think I'm old enough to be handling wildlife legally.. I'm 14 years old, but i want to help zoos with orphaned baby animals or help arrange cages or whatever I can do.. :P There was a summer program for my local zoo but unfortunately i wasn't home for the meeting and everyone was chosen already. i still really want to help. And there's only one zoo around me and they don't really have babies very often.. But I want to bottle-feed any baby animals and carry them around and just have fun. i was thinking tigers, bears, ect. Something that'll grow up to be huge and somewhat dangerous and even endangered that I can say I helped take part in saving. You know? i don't even know if this is possible for my age yet. But I still would like to know. Even helping baby dogs or cats or rabbits or any baby animal that needs help for a little bit, almost like a wildlife rehabilitator. Any information would be awesome. (: Thanks again.
