Mew can't be catched in Pokemon heartgold, only mewtwo.
I don't think you can catch MEW without a action replay. But you can catch MEW2 in Pokemon Fire Red or Leaf Green. You CAN'T cach mew without an action replay, but you can trade mew-two from the other games to the newer ones
mew is not catch-able on red blue or yellow but its is possible to use glitches to catch mew http://www.youtube.com/watch?v=Y3jv1PKrF0Y mewto is catch-able, mew is handed out at Nintendo specail events and that's about all
the only way to catch mew is to defeat the elite four

You can't catch a Mew in the wild. You'll need to trade for it or use the Action Replay.
You catch Mew-Two
You cannot catch a mew. You can only get it through events or cheats.
Mew can't be catched in Pokemon heartgold, only mewtwo.
On heartgold, it is only available through a Nintendo event. But another way is to trade from another game, where you might have caught mew. Hope I helped!
