Jellie is a shapeshifter and Katy Bee and Finnegan are aliens
Jellie has 6 legs and she's giant. She's Scar's familiar and changes into his different mobility aids. She automatically knows how much pain he's in and how much his muscles can take and changes into the form that best matches it.
Katy Bee and Finnegan crashed from space and inspired Scar's alien theme. They float and transmit sound into his brain (ex. They don't actually meow or purr they beam the sound into his head)
No one bothers to mention it anymore because Scar insists it's normal cat stuff
