cool stuff to get your kin friends:

stuffed animals/figurines/paintings/ect of their kintype

cosplay items for their kintype (i.e. ears and tails specific for animalkin’s kintypes)

toys for their kintype (like chew toys for dogkin, you can actually get human chew toys made specifically for folk needing oral stimulation right here)

food items that their kintype might eat (kinfood has tags for different kin types, usually easy to make recipes)

movies/books/shows that are revolved around their kintype

clothing involving their kintype (as a foxkin i really love orange or grey shirts)

give ur kin friends kin presents they deserve it
