Kenai's behavior has been confusing me a bit lately. Sometimes, both in the cage and at playtime (always when I'm playing with him or scritching him), he'll get excited and kind of bite and tug my hand/arm, make some squeaking noises, and then sort of mount my hand/arm, but no humping. I've also seen him do the squeak-and-mount with his fleece buddy a couple times. Is this just a puberty thing? He just turned one last week, so I'm imagining it could be. I don't really mind the behavior (except when the biting is a bit hard), but I thought I'd see if any of you have any insight... just want to make sure I'm not upsetting him in some way. Thanks!
