use the same properties as for humans?
We also have

Again: Do we have animal properties, or do we use the same as for
humans?
P21 is a subclass of P31 with Q18608871 which indicates in machine
readable interpretation that it is about the gender of people, yet the
descriptions assume items can be associated with P21 to include gender
of animals. Yeah, I can understand the confusion. :/

I don't think that P21 (
https://www.wikidata.org/wiki/Property:P21, sex or
gender) is a subclass of P31 (
https://www.wikidata.org/wiki/Property:P31,
instance of). Properties aren't subclasses in general.
Perhaps you meant to talk about
https://www.wikidata.org/wiki/Property:P21
(sex or gender) being related via (
https://www.wikidata.org/wiki/Property:P31
(instance of) to
https://www.wikidata.org/wiki/Q18608871 (Wikidata property
for items about people). This indicates that the property should only be
used on people, even though the description of the property itself talks about
its use on animals.
It appears that Wikidata is not very consistent internally.
