Over the past couple of weeks, the Feety Peets have received updates with fits for Inithium Kupra & Kario! They will also be getting Handy Paws and Hoofy Toes updates in the future.
Kupra’s peets have generally the same shape as the Maitreya/Slink fit, so anything made for that size will work for Kupra as well.
If you already own the peets and want to update, grab a redelivery from the inworld store.
