A full size garter came into my car via a garbage bag and went from the hatchback trunk into the back seat gap. I put in salmon but it was never eaten. I left the car doors open for 3 days. I found shed skin. I haven't seen it again but don't know if it left or is still in the car. The car was not used for one week while the temps were up tp 90 degrees outside. If it did not leave the car would it be able to survive in the heat? I read that they may not eat for up to 3 months so if it is still alive and in the car, at least it won't be starving. Any help would be appreciated. Thank you!
