The Legendary dogs are called dogs cuz of the story that they are reincarnations from eevee evolutions that died in the tower fire.
They more closely resemble a Lion, Tiger, and Panther if you ask me... But hey, if they are reincarnations, why couldnt they come back as cats? Some guy once told me he was going to come back as a tree to save the planet, so who knows.
As far as wanting to see new/cool cat pokemon, I'd like to see a Jaguar, Cheetah, and Voltron.
GT: NYNJUH Grunts are even prettier on the inside, that's why I use grenades!
