All 3 of mine are climbers but only Spike is a jumper. He's 5 lbs so its not as scary as Pearl but I still don't like it. I always say he thinks he's a flying squirrel because he can't just jump down from something, he has to jump way out too.
Good luck with your little Pearl. Sounds like her bones are made of rubber.
