K, here are all the cuties together, ready to kick butt.
Now I always saw Eevee and her evos as feline, mostly, in appearance. They have very flat faces in all the official artwork, and most eeveelutions have a sleek, cat-like body, so it made sense to me to draw a cat-like muzzle.
I have a theory that Eevees where made to be the perfect house pokemon and pets. The adorable face of a kitten with big bunny ears. A big fluffy coat and long bushy tail. The friendliness and playfulness of a puppy, but cleanliness and low maintenance of a cat. Hence why they’re rarely seen in the wild and why their DNA is so wack. They’re so domesticated that they can’t survive in the wild very long, so they evolve to better cope with their environment.
