My kitten was looking in a certain zone so I knew where to place the trap - Next day I found mr mouse in it. I have to make sure to place trap somewhere my 12 week old kitten can't reach as it is sensitive and I wouldn't want any of my beloved pets to get hurt. Hopefully next year my kitten will take care of any mice entering my home to escape the cold, but if not, these traps seem to do the trick - They preferred the fresh cheddar cheese over peanut butter, and the trap is really easy to clean and reload. Also the mouse itself is easy to dispose, they even include a stack of plastic gloves for disposing when you pick up trap
