Had that happen to me, way back in the day. We shipped on a Thursday and the snake did not reach me on Friday due to bad weather in one of the shipping areas. The snake did not get to me until Monday morning. This was during the height of summer, 90 degree temps ALL weekend long... it was awful.

The snake reached me... and he was fine. Mad as all get out, and a little dehydrated, but fine. Packaging has to be considered... if the snakes were well packaged, they'll probably make it.

Hope it all works out for you.
