Fan characters Eevees w/expressions.
Those aren't eevees. Eevee is the first form of all of those Pokemon. Once it evolves, it becomes an Umbreon, Espeon, etc. Not another Eevee. Also, it's kind of strange that Jolteon is pretty much the only one of Eevee's evolved forms that looks vulpine. Remember, they're not cats.
Of course, XD I still say Eevees regardless or do you prefer Eeveelutions more? Either way, means the same thing to me. Also about them being cats or not, Eevee and its evolutions are whatever you prefer/want to draw them as.
