Sam and I are moving back home to St. Louis, MO from Flagstaff, AZ. Sam will be transporting all 10 animals alone This monday starting at 4am. (i have to say behind to finish school until may 12th) We will be giving the ferrets each 1mg of melatonin to ease their stress and help them sleep during the car ride. How much melatonin should I give to Apollo (56lbs) and the cats? I want them to be relaxed and calm during the trip. Thank you!
