You go to the tall grass in route 1 and will find one. it may take a bit, but probably not.
No one in the game trades you rattata nor pidgey if you want to trade those Pokemon use a link cable or wireless adapter to trade with leafgreen or another firered.
find a friend with leafgreen who needs a rattata.
Rattata is a Normal type Pokemon C: Hope that helps--Taylor
