Kili was actually the first one to find the kitten. Bilbo would later take the kitten (which he named “Buttons”, which Kili thought was ridiculous) to show to other wounded dwarves to cheer them up, and Buttons became a healing cat. But at the end of the day it would always return to Kili.
Ok it’s been 8 years since I posted this and @heartoferebor pointed out to me that it looks like he got top surgery which, hell yeah Kíli same, but also it makes Buttons sitting right on him the MOST post-surgery cat behaviour of any transmasc’s pet.
Harry, at 'yer service. He/him.
