Cats do have fingers, four on each paw. They're just shorter than ours. They also have stubby thumbs part way up their front paws.
But enough of that. I'm prompted to think of other cartoon animals apart from cats.
Mice: Jerry, Mickey and Minny, Mighty mouse, Dangermouse, Pixie and Dixie, Biker mice from Mars.
Roger Rabbit and Bugs Bunny.
Donald and Daffy Duck.
Secret Squirrel.
The dog in Tom and Jerry, Pluto.
More cats: Mr Jinx (who hated those meeces to pieces), Thundercats, Korky the cat.
It looks like an outright win for the cats with mice second and the rest way behind. Unless of course you know different ---
