(Spoiler) You should be able to feed it by throwing but the eating radius is a little off ^^; going to push a build to fix that. In the meantime you can just lure it to eat your pets without throwing.
Oh, huh. I was able (SPOILER ALERT) to feed it by figuring out you were able to aim, and I felt really bad afterwards but.. the stuff we do for survival, right? I've tried luring it but the thing that works for me is is aiming the circle directly into the monster and then ... uh... blood appeared. Twice. So I guess I am doing something right :') Thank you for the help!! I will try to figure it out and try to feed it more to see what happens. Thanks again, means a lot ^^
