Jack and his sibs were born with a brain abnormality called Cerebellum Hyperplasia (CH) that gives them funny struts and effects their depth perception but they are otherwise unaffiliated and live perfectly happy and normal lives. Jack is a blast! He wants you to think he is a bad boy, but Jack is all love and cuddles. He's the big brother of Frieda's babies and looks over Zoe.... while they rough house like gladiators of course. He's quick too, the kind to dart out of an open door. If you adopt Jack you will always get a laugh out of his antics.
