I thought he was copying a cat or something. I finally figured it out but they do get aggressive especially when they are shedding. Mine actually latched on to my finger. Kind of funny but also terrifying.
I think it is good to bake them. It kills all the pests and parisites. Try to find thin and thick branches that fit in your oven. If you find a branch you like just cut it to fit and that should work.
You can tell if it is a boy or girl if it has a little spine on the back of its foot. Female if no spikes and a male if it does. I hope this was helpful.
