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?
You’d definitely find dry little black rice-grain-like droppings on all surfaces if you had mice, especially in rooms that have food, and more will appear if you clean them away. Also, little sticky splotches that are easy to mistake for drink spillages, because they pee everywhere too.
I managed to get rid of mine, but I occasionally still find evidence they were here in out of the way corners that I forgot about.
Brave mice - because I’m sure some will have that trait - and those infected with toxoplasmosis won’t care about cats.
Good luck.
I have mice active in my house and haven’t found poop yet, only realized last week when I found a piece of leftover food that was nibbled down on the edges. These ones are sneaky.
