Oh yes we had a mouse in our house, actually more than one and they were in Sydney's closet. I made the mistake of leaving guinea pig food in a plastic bag and I could not figure out why there was always a hole in the bag....then I found mouse poop. So now the food is in a Rubbermaid bin and I spent hours cleaning the closet and the mouse traps were set and we have actually caught two mice.
Syd's closet has an door that goes to the eaves and I guess the guinea pig food was a major invite to mice.
I have never had a rodent in a house or apartment and let me just say I was so grossed out!
