Will mice leave a house if they simply smell cats?
I think it depends on the cat. I moved into my house and after a while I started hearing squeaks and then began finding droppings in my clothes drawer. I even began seeing them run across the floor and under my bed. Put all my food in plastic boxes. I got traps, poison etc and caught over twenty in two weeks. After a couple of months it began to be less of a problem but I would always catch a couple every few weeks.Then over the summer I got a kitten. He loved to play with fishing toys. I got him a little mouse teddy and he loved it when I threw it or dangled it for him to try and catch and show off his ninja moves. Then I noticed there weren't as many moths around as much. There used to be tons of spiders but they started disappearing(I actually liked them a lot so I was a bit sad). I realised that my adorable kitten was a tiny psychotic panther who loved eating anything that tried to run from him.I tried rescuing a spider from the bath and my cute bundle of fluff went nuts trying to get the spider. I put it in a ceiling corner and my cat sunk his claws into me, climb up to my head like I was a tree, grabbed the spider in his mouth and ran off with it. He looked me in the eye as he tore it apart and then ate it. Then he trotted over and began purring and cuddling up to me.As he got bigger I realised I wasn't catching any mice in the traps. They haven't come back. I would've done the same if I were smaller than my cat.
