Espeon, oops, not there.
Persian then, it's fun to draw and probably the most catlike of the above. Also you can make it look evil OR cute without even going off model! Skitty is actually very hard to draw!

I'm not sure Mew really is a cat, was it ever hinted by an official source? Well, if so, it's like a cat foetus.

Zangoose is definitely a mongoose. Apart from looking more like one than a cat, it's so well know as to be stereotyped that some species of mongooses battle and eat snakes. Mongooses are definitely not cats, although they and cats are closer related than they are to dogs. Since mongooses are not ferrets [and ferrets *are* closer related to dogs] maybe the Japanese term for mongooses is catlike ferret or something, which is why it's the Cat Ferret Pokemon?

I also think Raikou is a cat [though the other 2 of the trio are doglike]
-Sabre teeth. No dog ever had sabre teeth, but 2 separate lineages of prehistoric cats did [and some hyenas, which are not dogs, and some marsupials]
-Tiger stripes. Dogs don't have stereotyped tiger stripes
-Long tail with tuftish end aka lion/feline. Few dogs have this. Stereotyped feline characteristic
-Small tigerish ears. Only a few dogs have small rounded ears, most big cats do.
-White ruff around face like a tiger
-More catlike body shape
-Stereotyped tigerish colouring, black on yellow [no tiger is really yellow, but it's stereotyping
-Short, round cattish head rather than long Suicune snout, without bulldogish or Pug features like Entei

So Raikou is a literal take on 'sabre toothed tiger'. Of course the Sabretooth Cats weren't really tigers, but it's a design inspired by that stereotyped concept.
