The weird part is if he can go with me he always does. He has never got carsick. Even when we took him on a road trip going down the Oregon coast, he never once got sick. Then once it got so hot he had to stop going with me everywhere unless I wasn't getting out of the car. Then out of no where on the way to the vet he threw up 2x. I thought it had to be a fluke, but it has happened 2 more times. I noticed before he threw up last time all the drool, which is the same thing he does in his cage when we are gone. I am a stay at home mom, so I am here with him most of the time but whenever I have to leave he absolutely freaks out. Thanks for all the advise, any more input is welcome.
