The quality, state, or condition of being feline; the essential characteristics associated with cats.
From feline plus the noun suffix -ity, which creates abstract nouns from adjectives. This follows the Latin pattern feline → felinity (similar to serene → serenity).
There's actual neuroscience behind felinity: cats' brains process things differently than dog brains—they're more aloof because their brains are wired for solitary hunting rather than pack behavior, and this literally changes their personalities.
