Eevees
Yes!! They are adorable. In fact, all foxes are cute! EEVEE IS NOT A FOX IT IS A SOMEHOW ADORABLE MIX OF DOG, CAT, FOX, RABBIT, AND CUTENESS BUT I NEED A VAPOREON! I'M SO SAD
the way you get two eevees is..........I don't have a clue i just want a swinub there so cute were do i get it! its driving me nut!!!!! anyway this is how go to bebe then go to the cave in the Pokemon league and press select,start,L,R,A nonono don;t do it it resets your game.
Girl Eevees are rare. Because more than 95% of the time boy Eevees hatch instead of Girls. Out of my overall 60 Eevees, 55 are boys. But it is possible.
It will be luck because i have 33 Eevees and 27 of them are boys. Boy Eevees are more common.

No, unfortunately, you can only get more eevees in crystal version is to breed one.
Yes. All eevees can matewith all other eevees in diamond, pearl, and platinum.

Breed with a Ditto.
Get a ditto and a leafeon and you will breed eevees. Then evolve them with a leaf stone. You can breed eevees with any evolved forms. It is not possible to hatch eggs as leafeons.
No.
