Did I ruin my boa

[Reddog]

So i needed to get some dog food today, so i went to one of the big pet stores today to get the feed for my dog and i thought i would get a mouse for my brb. The small pet store normal lets me pic one out but here the just went to the back and grabbed one. So i get home and look at the mouse and think this is to big for my brb. So i think ill try to see in my boa will eat even tho its about to shed. Bam strikes for it but nail the side of the cage so i thought i would wait and see if he would eat it. But i came apparent to me that the snake was in more of a defenseive mode as he struck the mouse but then did not constrict. So i thought i would grab the mouse out but with toungs i would have by hand but this snake was very up set . Well he started to hiss real loud and was trying to strike me and anything around as i was setting his hides back in and what not. he was a really good snake and i know shedding can make them not want to eat and easly aggravated . But do you think this traumatized my snake is he going to feel unsafe in his enclosure? Should i move him to his new one sooner than i was planing on?
