WP:Lead would suggest that the lead should have fewer paragraphs. In particular, there's something odd about a para that has "also" in it's opening.
Cats rely more on smell than taste, and have a vastly better sense of smell than humans. Does any mammal hunt by taste? Seems odd. Also, can repetition of smell be avoided?
Nomenclature and etymology
why does only French get a pronunciation, I'd lose that.
Including Basque is a bit misleading. The others may well have derived from Latin, but Basque isn't Indo-European, so this must either be a borrowing (rather than derivation), or, less likely, coincidence
Inconsistent and sometimes incorrect capitalisation throughout. Wildcat is variously capitalised or lower case, felid is incorrectly capped, Jungle Cat is capped, House Sparrow isn't, please check all capitalisation issues
A group of cats is referred to as a "clowder"... This para needs full referencing. I've never heard of "clowder" or "gib". If these are indeed current names, where are they used? If they are technical terms, say so. "molly" or "queen" — I suspect that she-cat is more common outside the fancy than either of these
"kitten" (which is also an alternative name for .... What's the point of the list, nothing to do with cats
Linnaeus bit seems odd, the text says 10th edition, but ref and link are to 12th. Also you don't need a retrieval date for a book or journal which exists as a hard copy. I don't think Carl will rewrite this any time soon
Genetics no GA concerns
Anatomy
You need to make it clear where you are talking about domestic cats, and where, as with much of the anatomy, it's Felis in general
Why the comparison with humans for vertebrae but nothing else? seems incongruous
Diseases subsection unreffed, should be easy enough to find something
Behavior
seven to 28 hectares (69 acres) only partly converted to imperial
Ecology
South Island Piopio; Chatham Islands Rail;[ Auckland Islands Merganser;[172] and the common diving petrel[1 inconsistent capitalisation of species. Zino's Petrel is another species driven close to extinctiom by cats
Domesticated cats
why is number of recognised breeds only given for the US?
sweet voice points to human voice. Is this intended?
First para of "Waste" is unsourced and a bit"how-to"
Style of coat pattern and body types subheads makes them indistinguishable from the items listed under each heading
Refs generally OK, although if this was FAC I might query how RS some are. You are inconsistent with author names, sometimes you give first name (or initials) followed by surname, sometimes the opposite. It's also preferred to write journal names in full, not abbreviated
Some binomial in the references are not italicised, I fixed a couple but not all
Images
I feared that this might be jam-packed with icky pictures, but in fact I would only query the second white cat image, which adds nothing
I edited the captions (removed forced image sizes, unnecessary repetition of article title, remove full stop when not a complete sentence)
