Kenma was about 5 when his mom got him his first pet, which happened to be a baby kitten.
He'd take the kitten everywhere he could and treat as if it was his own child.
Kozume would do things like feed it milk, tuck it in the bed, and play with it.
~Bonus: Every time Kuroo would over to play, they'd pretend to be a family and make the kitten their baby, Kuroo the dad and Kenma the mom.
