As far as my state goes, I dont believe so...if you trap for a living, selling fur to a wholesaler should be no different from selling the skull to me. And no on the rabbit and squirrel. I would think it would be base on your states laws regarding the sale...by no means do I want anyone to break the law to sell me skulls...I can obtain them legally in my state. I was just trying to make some new contacts for specimens is all...
