Walk in the grass on route 116
You can catch Skitty in Pokemon Omega Ruby and Alpha Sapphire in the barks of trees.
Catch a skitty near rustboro city then use a moon stone on it to get Delcatty.
The only way I know is to look behind the Pokemon Mansion or to migrate one from Ruby, Sapphire, or Emerald.
ruby
Ratls is easy.Skitty i got trading a women in pacidolog or something like that.
Skitty can be found on route 222 by sunnyshore city on a certain day because they are swarm pokemon. In ruby and sapphire they can be found on route 116 at a 2% chance.
skitty
No, Skitty is not in that generation.
Use a moon stone.
Migrate from Ruby, Sapphire, or Emerald.

Catch it in route 116
