Small Block Shack ForAll Your Yard, Garden & Outdoor Living Needs

I live in the desert and now that it's summer, the house is heating up. Hubby and I have lived in the heat our whole lives so we keep it up around 86-87 (when it's 115 outside, that's not as bad as it sounds). We really don't want to raise the whole house temperature, but we are concerned about the ball python. His cool side is right at 87 and he's nearly always on that side, so I think he may be a little warm. He is otherwise eating perfectly fine, shedding fully, active; he actually looks and acts great. We have a hide log and a bathing water dish on both sides of the tank so it's not the accessories that keeps him on one side. He has an under tank heater on the hot side which I found he much preferred during the winter, and the cats can't knock it off. All the python care sheets show that his cool side shouldnt be over 82, so I'm concerned of the long term of effects of him not being able to cool that low. Any suggestions from python breeders/keepers would be great. Thanks!
