like I already told you in the other thread. Don't take any animals with you, you will face the problems latest in Libya and Egypt (Qaranteen)
Tunis no Carnet
Libya Carnet avaiable at the frontier no problem but extra 100Euro
Egypt you need a carnet from the country of the car registration and the carnet has to be valid for Egypt, if not no way through.
It is expensive but no way out.
please think also about the fireextinguisher for the egypt frontier, if you don't have any, never hand out your car papers, better to give the person asking some money or buy the extinguisher at the frontier with a much higher price
