We basicaly have walking lizzards and cats bouncing all over the place... so why not the Avians? They dont have to fly.
Gliding alone would be a cool power. The tech exists for reduced gravity. Caitians have the innate ability to jump higher. It would likely just be a reduced fall speed but if they really outdid themselves, it could be a reduced fall speed or maybe a flight that caps out at around Caitian jump height, without the ability to jump while flying, kinda like the levitating ghost costume in ********.
