My igs room is in the attic. With my bedroom. Great in spring and fall. In the winter he has heaters. What can I do to help him stay cooler in the summer? My bedroom has its own a/c. I've opened his window a few inches to help keep heat lower. I live around Provo,UT. It gets up to @105 degrees in midsummer outside. He can come downstairs if he wants,but he's a big loner. The only time he's come down because of the heat, he was super aggressive. Any suggestions?
