How to take care of your Kat, by me:
First off, a warning will destroy stuff. whether it’s on purpose or by accident, it doesn’t matter, stuff will be broken either way.
Sleeps wherever she crashes, so beds or nests areen’t mandatory, but if you do, a dark corner or someplace above eye level is preferred.
when it comes to food, human comfort foods aren’t ideal for her health, but she’ll still store quite a bit. mostly, flesh is what she eats, whether animal, human or her own kind. very so often when molting, she’ll also eat iron and lead.
Baths are a point of contention. she hates water. humidity in general is a big no from the big fluff. Instead, she’ll burn trees to ash and use the still hot cinders to burn out parasites grime and other problems in her fur.
Bonding is an important part of forming a pack with a hellhound in it. Touch plays a huge role in doing so. Whether it’s piling together in sleep, or just petting her head for a good job well done.
Hopefully this helps a bit in your attempts to tame befriend a Kat.
