Two hours out of Mérida it was SO HOT! The cat started panting because he was over heating and was in real distress. We pulled over and put some ice in a plastic bag and put it in the carrier to bring down the temperature for him. We didn’t turn on the air conditioner for us because it would reduce the power and with pulling the overloaded trailer, we needed all the power we could get. So the cat had a swamp cooler and we suffered.
