Heeee~h... The only one of mine that I make sure to brush everyday is Hina, my Arcanine. I rotate the rest of them out too often now to groom them all everyday... I'd never have any free time if I spent it all brushing the ones who would need it.

... if nothing else, it should be easier to groom an Espeon. Their fur isn't nearly as thick as an Eevee.
