How do you catch a Delcatty in Pokemon Emerald?

You can't catch a Delcatty in Pokémon Emerald. Delcatty was introduced in Generation III, but only in Pokémon Ruby and Sapphire.

In Emerald, you can catch a Skitty, which evolves into a Delcatty when you trade it to either Ruby or Sapphire.

Here's how to find a Skitty in Pokémon Emerald:
