I just found out that my neighbor that I share a wall with is moving out because of “the mouse issue.” This is the first I’ve heard about it. I’m pretty sure I don’t have mice. I haven’t found any chewed food packaging or what looks like mouse droppings. I do have a cat but I’m not confident he would know how to kill a mouse. I’ve never seen him chase anything on the floor but I know he will chase flying insects. I also haven’t been presented with any “presents.” Could he really be keeping the mice from my apartment by just his scent?
Mice can often find ways you wouldn’t believe, but they still have to adhere to the laws of physics, so you might simply not have suitable holes in your apartment for them to enter. But yeah, also quite possible that they can smell the cat and don’t want to enter the lion’s den.
