1. A fourth exception to the prohibition of trapping on Shabbat applies when trapping occurs as a result of an act intended to ease one’s own discomfort rather than to trap. For example, one may close a door or window with the goal of relieving discomfort, such as keeping out the cold, even if an insect will be trapped inside as a result. The reason is that in cases where trapping is forbidden only rabbinically, such as with an animal or insect that is not normally trapped to use it, trapping that occurs without specific intent is permitted (Mishnah Berurah 316:5).

2. According to this principle, the following case would also be permitted: A partial act of trapping that is forbidden only rabbinically, such as closing a door or window to keep out the cold when a bird or other animal is inside and is easier to trap than before, but cannot be caught in one swoop (which is what determines the Torah prohibition, as we have learned previously).
