kagami gets a cat and names it kagami number 2. except kuroko is not afraid of cats and nigami is actually really fat and lazy because kagami spoils him. also the cat adores nigou and hides in kagamis gym bag so he can come to practice
GUH oh my god that's so cute. Kagami with a fat lazy cat who he pampers a lot and he gives him fatty tuna because Kagami's rich man he can afford these things.
OH OH and the first time Kagami brings him to practice everyone's like AWWWWWW A BIG FAT KITTY AND HE'S SO FUZZY 'N CUTE HE LOOKS JUST LIKE YOU KAGAMI and Nigou is there in the corner nudging a basketball back and forth because no one wants to play with him and UGH CUTE ANIMAL HEADCANONS THIS MAKES MY HEART FUZZY STOP IT I'M MEANT TO BE A BADASS.
Alternatively the cat could just be Garfield.
Which would be fucking awesome also.
