So, ive had my bp for nearly a year. He was an adult when I got him, and he's about 6or so years old. Always been really great, no problems, and no tempermant problems....until recently. It started a few weeks ago. Temps stay at 80 and humidity between 40%-60%. He started acting very weird, like not hiding, rubbing on ceiling of enclosure, and basically roaming. I thought he might be hungry, even though he just got fed, so I gave him another rat. He ate no problem. I've tried handling him to see if that might help, but he acts weird then, too. He wanders and is very restless when I handle him. I just opened the front of the enclosure up, he wasn't in any defensive positin, no ready coil, so I thought nothing of him, at that point, as I was just checking his water. I set my hand down in the cage and he bit me. No coil or wrap it hanging on, just quick and let go. But I was very surprised, as he has never bit anybody before. Nothing in his environment has changed, other than his light. His old one burnt out (ive changed his light before) and that was about when it started. It just exploded, thankfully I had him out at the time. I just replaced it, and hope that gets things back to normal. Other than that, nothing has changed. Any insight, here on this???
