I am leaving tomorrow for a 29 hour drive. My tortoise will be with me (about a year old, small, greek). What is the best way to transport him with me in my vehicle and where can I find something to generate heat, like a heat pack, etc? I can't order it online because I waited till the last minute! (so much going on) so it's too late now. I am leaving in the morning. Any ideas? Thanks so much!
