Jim

A street cat who decided YEP the doctor is my person now and the Tardis my home. Also snuck in and KEEPS on sneaking in every time the doctor tries to throw him out and shoo him away. Now the Tardis is sentient to an extend and can be rather cheeky. And I like to imagine it rather likes Jim :oP and every time Jim sneaks back in again there's a new piece of cat furniture added to the interior of the Tardis. like a scratching post, one of those climbing posts, shelves for it to walk around on, a tiny hammock and various cat toys. I imagine Jim to bring the doctor and Elisa to crazy places by just walking on the control panel and pressing a bunch of buttons. or Jim locking out the doctor on accident because he played with a string tied to a lever
