Cat, Kitty, Feline, etc. species

The Cat, Kitty, Feline, etc. species was a species of Cats, Kitties, Felines, etc. Their society was divided into the four groups listed below. Kitty Witty was a Cat, Kitty, Feline, etc. Anyway, these little guys were very good at persuading people do do stuff because of their big cute eyes and their fluffy fur and...well, you get the point.

Cat
Usually the big, fat, lazy ones. They didn't really do anything except eat.

Kitty
These were the cute one! Everybody loved them because they were so cuddly, wuddly! Sometimes they could be a real pain in the ass though.

Felines
These were the geeks of the species. They usually got jobs as scientists and crap like that.

Etc.
How the hell should I know what this means? It probably means some other cats, or kittys, or feline. I don't know.
