Bardic magic!
Minor bardic magic makes a cat's voice, even when speaking, unnaturally alluring and melodic. Cats will find themselves more willing to listen to a cat with minor bardic magic when they are using their magic, and cats with minor bardic magic can use their magic to alter the emotional state of those within earshot to some degree (can bolster, enrage, instill fear/paranoia, depress, etc.)
Major bardic magic allows a Storkie to magically alter the emotions of those around them when speaking or singing to much stronger degree and with more effectiveness. They can use their magic to be nearly entirely believable when lying, though if it's glaringly obvious the magic can be resisted if the effected tries hard enough
Paragons have metallic silver tongues, and can animate objects no bigger than a hare around them when singing. They can physically damage others with their voice (typically with burn-like wounds), and gain a glittering wispy glow to their eyes
A Storkie with any level of Bardic magic will exhale purple mist when using their magic. It's rumored that breathing the mist increases the effect of their magic (if it's altering the mind or emotions of the effected), but this is a myth
Eyes range from mid to dark (saturated) purple
