Can you post the temps coresponding to the shipping time.
It was above 60 F at both locations. Exact temperatures... I'm not sure where to retrieve them! I based the no heat pack decision on the last shipment I sent to a southern state - the reciever told me when the package arrived, the internal temps were right around 100 degrees.
This is just a personal technique, but when I ship a larger snake, I generally cool them for a few days at home before shipping them. This way, there is less shock to them when they are subject to slightly cooler than normal temperatures overnight.
Is this the same Mark and Amee that let their rescue iguanas free roam in one room, whether male or female?
I'm not sure what this has to do with the issue at hand, but yes, that would be us. At one time (while I was actively involved with Colorado Reptile Humane Society), we had anywhere from 30-40 adult Green Iguanas free roaming in one room.
Iguanas take a massive amount of space, and setting up individual cages was not practical. The way we chose to free roam the igs was a bit of an educated guess... It took a good balance of males to females. The males generally had a group of females they would defend. If the chemistry of the room was tipped off balance by the introduction of a new male, we isolated that male to a different room until things calmed down again.
This setting worked great - we heated the entire room to 80 degrees and provided basking areas and UV with mercury vapor bulbs.
If I ever get back into the iguana rescue world, I'll do it exactly the same. Only with NOTHING else in the room (no snake cages).
Anyway, I lived in CO for several years and the weather there with the exception of the mountains really never does have a day the sun doesnt shine. I am not sure if it is warm enough to ship without heat packs though.
Colorado is a large state that changes drastically as you travel. Denver can be 40 degrees, while Colorado Springs is 60, and Pueblo is 80. They're all right on I-25, and about 90 miles apart total. As I stated, the temperature when we shipped was right around 60 degrees.
At what point would you deem heat packs necessary, or unnecessary? I made a judgement call, and so far it doesn't seem like it was a bad one. There was no mention of the snake being cold. Only unsubstantiated claims of the snake being "half dead". Which half was that?
