Not to call anyone out here but breeding dogs with hip and breathing problems is totally a different thing. Not being able to breathe or walk properly is painful... the wobble is not. I would never own a great dane for example because their hearts are too small for the size so it cannot keep up giving great danes a short life span. To me that is unfair. But the wobble does not effect a spider or woma in any negative way. I am bringing woma into this because I have one that has a worse wobble then my spiders. I do not think the wobble brings "personality" to a snake and I believe this statement is just used as an excuse for the wobble. My grandfather died from dementia, beside forgetting a few people and bit of memory loss, his personality never changed. The wobble does not effect my spiders or my woma at all. They may miss their meal but it's nice to see these guys not give up and hit the rat on the second try. I do breed these guys and right now my woma who is also fire is breeding to my vanilla. If I get a woma vanilla cream, wobble or not, I am super excited to see the outcome.
