It says in the D/P Pokedex that Meowth learns Pay Day at level 30... but it evolves into Persian at level 28... does that mean that a Meowth can't learn Pay Day if it evolves into a Persian at level 28?
No. Persian doesn't learn Pay Day. If you wanna have a Persian with Pay Day, wait with evolution. If your Meowth gets level 30 and learns Pay Day, then evolve it.
Erm pardon me if i am wrong, but i think when it reaches level 30, it will learn payday immediately, then following that just allow it to evolve, so it can evole at level 30.
Yeah that is a very good way to stop them evolving if you dont want to keep pressing b every time it goes up a level, like when I do that I always forget to press b because I stop paying attention and then my pokemon evolves so i have to restart my game from when I last saved.
