I'm giving my Piggy away this week and the lady who is taking him lives about an hour and a half away from me. I'm wondering about the best way to transport him. I have to take his tank apart to move it so he can't stay in there for the trip. I'm also thinking it may not be the best idea to just keep him on my lap in case he tries to run or something. What's the best way to transport him? Cardboard box or something? How should I make sure he stays warm etc?
