Sitich started doing this one day, and at that point I still thought he was a she because that’s what my friend who gave him to me told me. I found out differently that day. lol. My arm was crazy scratched up, and he liked to hop up behind me on the couch and munch on my hair when I wasn’t looking. He did this for a couple weeks, and I gave a stuffed frog that I gave him to let it out. It honestly did seem to calm down a lot after a few weeks. I did have him neutered and since then the only time I’ve seen him hump anything is when I was starting to the bonding process with Mumbles, and now I never see it.(I didn’t have Mumbles when he first started the humping behavior)
I was terrified too when I took both my buns in to get neutered, but honestly they both acted like nothing had happened to them. Mumbles no longer marks his territory like he was doing, which I am so grateful for. lol.
