My boy loves his tree branch. His second to last feeding he decided he wanted to eat in the tree. He climbed up it and would not come down. The first mouse was eaten on the ground because he lunged off the tree branch. The second he would not come down for and ate it upsidedown hanging from the branch. He really loves it. It has a lower area where it's only an inch above the ground and I often catch him stretched out there with his tail wrapped around the top of the perch area. I don't think it has anything to do with the heat. It seems to be his lookout post. I often catch him starting at whatever I'm doing from there.
