Catgender: 'where someone feels that the closest way to describe their gender identity is by making the equation to a cat in particular, cats in general, or by comparing their gender identity to certain cat-like features.'
I found out today there is a range of subtypes, including
Meowgender: 'people who feel strongly connected to older and/or full-grown cats. Meowgender people have various reasons for relating to older cats, such as personality, behaviour, or aesthetics.'
Presumably the subtypes share an impulse to disrupt events held by cisfelines (those born as cats), and demand equal access to litter trays.
