I’ve always thought that Eevee was a dog, as it resembles a dog; its physical characteristics are that of a dog along with its personality traits depicted in the anime, etc. But I could see fox too, which would still make it a member of the canid family.
Those that are saying cat: I could see that as well, but only in some of Eevee’s evolutions, and not because cats are smarter. That’s just laughable. Cats are killing machines and not really all that affectionate unless it gets them something. They’re also solitary animals, with the exception of lions. The smartest animals on the planet are Humans, apes, chimps, dolphins, dogs, seals, and some birds. They all have one thing in common: they’re all highly social animals, which contributes to their intelligence as a whole, and can’t thrive on their own.
Cats don’t need that, because they are simply not wired that way, resulting in limited intelligence. And using the litter box is not a sign of intelligence, it’s instinctual for them to cover and hide their scent from other predators.
Dogs are simply more intelligent than cats, that’s not even a debatable fact. Glad I could clear that up for you all.
Like I said, if I had to guess - Eevee is more dog like. And the reason the eevolutions look so much different, could be to let the trainer evolve to their preference: whether they’re a dog person, or a crazy(overexposure to cat poop causes toxoplasmosis, which makes one more prone to mental illness) cat person.
