I wouldn't worry if your snake skips a meal here and there. I usually tell people to double check the temperature and humidity, but it looks like you're doing fine there. Here are a few things you can try to get your Dumerils Boa to eat a little more consistently. First of all, I prefer feeding using tongs rather than leaving a rodent lying in the cage. Sometime a simple wiggle is all it takes to get your snake to take the food. Also, if they're hesitant to strike but are still interested in the food, you can apply gentle pressure and they'll take it. I'll attach a video I recorded doing this with one of my Brazilian Rainbow Boas. The last thing I thought I'd mention. My 6 foot long Dumerils Boa, Lazarus simply won't take rats. However, he'll take a mouse every time. I just feed him a tiny mouse, then follow it up with a large rat. I hope this helps you out.
