Boas can be strikers, that's just how it goes. If you want to try to diminish the frequency, you may need to hang a sheet or something in front of the cage from here on out if it bothers you. I think I mentioned earlier(?) walk by/do anything in front of the cage realllly slowly, like slow mo, they usually won't strike when I do that (just sit in the 's' position watching you very intently lol). Some are more prone doing this than others and it's most likely not something you can break them of. She may not do it as much once she's fully mature and doesn't feel like she needs to feed to grow but no guarantee. And yes, boas can stay in feed-mode for a long time. Been keeping boas for a while now and have hardly ever had anyone get injured, a tooth through a lip is about as bad as it's gotten for me.
