16 month old male BP - started striking in the last 2 weeks

[HNECdn]

Hi,

** I value and appreciate the advice on this forum, and am grateful that the primary concern is the snake. That being said, there are a few things in this post that I have done seriously wrong. Please be kind, I only want whats best for my BP's as well. We are new-ish owners (1 year now) and care about both of our critters dearly. I, as the adult, have relied on advice I have been given and am learning as fast as I can. Whats happening is truly breaking my heart. Thank you in advance.

My 16 MO Male Het Pied BP, has been a very laid back and cool dude ever since we got him at 3 MO. He had a bad shed about 2.5 weeks ago. I bathed him for 20 minutes and spent an hour afterwards helping him with the shed (I think this was what did it). At the end of our shed session, he peed on me. At the time I took it as lots of body manipulation contributing to him peeing. I now realize this might have been my fatal error. The next night, we repeated the process and spent 20 minutes getting more shed off. He still has a small piece on the back of his neck, just down from his head, about an inch and a half long, and half way around. A few days after I had helped him out, I made another major mistake and left his door open on his terrarium (Please be kind, I'm in final exams for full time university and working full time, it's been crazy, and I was too tired). I noticed it the following morning and found him in about an hour. He was VERY cold and I put him on my body and warmed him the best I could replacing him in his terrarium.

The next day, he FLEW at the glass and struck it when I walked by. He has never done this before. I took it as a sign of severe stress and left him alone for about a week. He ate very well last weekend and I had him out for 5 minutes a few days in a row, leaving me to think he had somewhat recovered, but not pushing him either. Tonight (about a week later) he struck out at the glass again. I'm heartbroken that we have done something that has permanently changed our relationship.

Husbandry: Temp is good. Terrarium is too high and its very difficult to keep ambient temp up, but it's around 75-80, hot side is at 90 at the glass monitored with a thermo. (We are getting new terrariums from Cornel's World soon to help with the ambient heat issue. We also have space issues with our 2 BP's and these terrariums are stackable). He eats 1 jumbo mouse every Monday and has never refused a meal, even after this. He is about 38-40 inches long, I don't know weight, but I'm pretty confident he's a good weight.

What do I do, and what do I need to know... Could he be sick?

Thank you,
Heather
