I am going to London from Manchester tomorrow (3-4 hours), (My snake seems happier since I fed it, I think it tired itself out when it shed and went to the toilet this week) I have a large cooler bag (insulated bag) and a square juice bottle (won't roll) with warm water (i've tested it over the day and it doesn't leak) I will put my snake in a pillow case with newspaper and put it in the cooler bag with the top unzipped, the ambient temp is 22 deg C (71.6 deg F) and the bottle is 26 deg C (78.8 deg F) using a mercury thermometer. This will be placed on the floor of my car. Is this setup ok? I can change the temp by changing the water in the bottle, the water will cool to about 21 deg C after 5 hours ambient temp about 19 deg C.
