Sorry about your bunny, CG. We had a Holland Lop male bunny who died of a heatstroke while we were moving from Missouri to Colorado. The air conditioners in both of our U-Haul trucks broke and it was over 100 degrees driving through Kansas in the middle of August. Fortunately, our daughter, who was a baby recovering from open heart surgery at the time, was OK.
fuck the daughter, what about the bunny!? what was he doing in a u-haul truck? you should always carry pets in your lap if possible. i'm worried about taking my kitty on a plane, they don't let you keep cats in yours lap.
We were moving, so he was moving with us. He traveled on the seat of one of the trucks, not in the cargo area. If the air conditioner in the trucks had worked, he would have been fine.
Most airlines will let you have the kitty in a pet carrier under the seat, but if the carrrier is too big to fit there they make you put the pet in the cargo area.
