I don't want to be the one to say try but. I live in Nevada just hours
from Southern Cal. For the most part you should be fine. Check
<http://www.cdfa.com/> for info on ferrets in Cali and what happens
if your caught. I believe the check point is closed on Sunday.

there are alternate routes and more info.

If all fails let me know I am in Vegas and will help all I can.
