The q-tip in the vent is the least of my worries. All the prey you just mentioned is too small. My snakes might get a pinkie or two before they are on to fuzzy rats and then pups. Most of the live mice you get at the store if that’s the only place you have are 15-20 grams. Snake should have no issues with that. We can’t be inside your husbandry all the time. Live prey especially a mouse is a good indicator in my opinion if something is truly off. I have rarely if ever had a BP refuse a live mouse. I’d also try smaller hides. Those open air hides have never seemed to work when people post on here. My concern is it sounds like you are looking at that as a last resort (live mouse...) I would say if you try shoving mashed up dog food down it’s throat it will only make things worse. Same with force feeding. You have no experience in either. Sorry just being honest.
