Felicity and Louis sole purpose is to serve humans the best the can but their previous master trapped them in a mystic bottle due to them being very powerful which their master feared would have been bad for the world. But before we got on with the story let's talk about the two: They are both magic cats who look like a unicorn/butterfly. Felicity is very energetic, fun, bouncy, hyperactive, enthusiastic and free-spirited cat and Louis has a high-strung, shy, and has a tense demeanor. He is genuinely scared of most things, He is very timid and fearful, but when faced with adventure, he will (though reluctantly) gather courage and bravery for his friends and sister. As cats, Felicity or Louis sometimes cannot fight their feline urges, such as putting a bird inside his/her mouth or wanting to chase a mouse. Despite them both being sealed away for so long, they are both aware the world has changed a lot.
