Yup. Noctowl can be caught by headbutting in Illex Forest or Viridian Forest, and in the grass on Route 14 at night. Also probably on Route 47 at night, but I think that's Hoothoot. If you know if it's Noctowl or Hoothoot on Route 47 at night, be sure to fix this answer. You need a membership to do so.
you cant catch persian in heartgold.... i think
You'll need to trade for it from Pokemon HeartGold. It is not avilable in the wild in Pokemon SoulSilver.
it depends the game you have, but if you have pearl or probably any other pokemon game go to the pokedex and look for the pokemon if you find it click on it and go to the part of the map there it tells you if its found or not
yes, but not heatwave
You have to be able to go in the kento region, then go in the: Viridian Forest, and while in there, you should run into a wild Pikachu, catch it, and you have your own Pikachu
it will appear by itself in the wild.
Both! Noctowl appear in the grass and Hoothoot appear by headbutt.
It makes wild Pokemon appear more often :( or :)
It may appear in the Burned Tower or you can find it in the Safari Zone at night.
How come nobody knows the answer? Edit this answer if you DO know.
yes
After you go to burned tower it will appear in the wild randomly. how you catch it is up to you (personally I would use a master ball)
No, it is not wild
i think u can only obtain him by event. But there is an ActionReplay code to make him appear in the wild. Look up that code. Hope i helped!
Sneasel cannot be found in the wild in HeartGold/SoulSilver.

You can't get a wild Eevee. You can, however, receive one from Bill.
