This looks pretty cool!

query.wikidata.org has 59:

I wonder why the difference?

Also, looks like your query:

    WHERE JSON_EXTRACT_SCALAR(item,
'$.claims.P31[0].mainsnak.datavalue.value.numeric-id')='146' #cats

only checks the first claim. But there could be more than one P31 claims
in Wikidata.

More cool examples! :)

That's hard to say - properties can vary a lot, especially depending on
kind of items (birth date useful for humans, less so for buildings or
paintings :) So it probably has to be rather flexible to cover varied
cases.
