How do you catch a espeon on Pokemon?

You can't catch Espeon in the wild. To obtain one, you must evolve an Eevee into an Espeon. To do this, you must first raise your Eevee's friendship level to at least 220. You can do this by battling with it, using it in Pokéjobs, or feeding it berries. Once you have reached a friendship level of 220, you must level up your Eevee during the daytime in order for it to evolve.
