A long time ago i released my quilava into the wild and when i checked the area for him on the pokedex it said he was in the area where i released him and even when i went to go catch him again i found him. if you let pokemon go long enough will they breed and will you be able to catch them regularly
No, you can't. http://bulbapedia.bulbagarden.net/wiki/Released_Pokémon They are gone forever.
