My boy is acting weird

[Homebody]

Lately he's been striking when I open his enclosure and I can't figure out why. He just seems extra moody. I'm wondering if this is him coming of age and if this is just normal breeding moodiness. He's eating normally. He eats small adult F/T rats every 2 weeks. His temps are normal, 74-77 cool end, 88 for his hot spot. Humidity is fine, around 60%. His sheds have been good and in one piece. He's pooping like normal. Nothing dramatic has happened lately. I upgraded his hides but he was acting like this before the upgrade. He's a pet and my only reptile.

I doubt this is the cause, but your cool side temps seem low to me. I'd bump them up to 78-81F.
