This thread helped me a bunch! I have 12 royals currently and all but One are eating. The one not eating is a large, slightly fat adult male that I bought from Ken Macek. I was worried I was doing something wrong, but was clueless since all other 11 pythons eat fine. Now I feel better knowing that big adult males often fast during the winter, and especially if they are chunky!
I got the adult male a couple months ago, and he hasn’t eaten yet for me. No big deal I guess.
this is my first time keeping a large adult male.
