Exactly. I have a bunch of eevee's that I bred xD
Or if you don't have ditto you can also breed an eevee with another species of the opposite gender that's compatible, like pikachu, nidoran, snubbull, bidoof, whismur and various others. But if you want to get another eevee, the parent eevee has to be female and the other specie has to be male. When breeding two pokémon of different species, the resulting egg will be of the same specie as the mother
Sorry about the off-topic though.
