My bumblebee, Rio, all of the sudden overnight developed a bad wobble. Ever since I got him he barely had a wobble, just a tiny head shake like he's shivering. A couple nights ago he was doing full spirals and trying to slither around upside down which I had never seen him do before. It's heartbreaking to watch. I guess the good news is that he only does this when he's in his cage. It's almost as if he's completely fine when he's out of his cage...he's never liked being in his cage though. He prefers to come out lol I still love him to pieces though.
