How Ya Gonna Keep 'em Down on the Farm After They've Seen Paree?
Once my male panther had gotten out to explore once or twice, he began charging me whenever the door was open. Normal enough once other possibilities have been eliminated (and I'm not seeing any glaring issues aside from basking temp being on the high side).

Lowering basking temp is a simple matter of raising the light a couple/few inches & monitoring the temp. If it doesn't work out or there are problems, it should be easy enough to move it back.
