Mice are amazing. I lived in a new home, in rural area, and never suspected that I had a mouse problem. One day the oven gave off a really funky odor while baking. A bit of investigation revealed that there was some dog food hidden in the inner working of the stove. A complete disassembly of the stove was then required, since the entire stove was packed full of dry dog food, literally several pounds of it. A mouse, or maybe a posse of them, had carried the big dry nuggets about 20 feet, crossing the kitchen, until they completed the mission, and never got caught. Now we didn't have a cat on scene, just a Golden Retriever, who was very lovable, and extraordinarily useless in matters such as this.
