Mice can be an unhealthy and irritating nuisance within a household. Since cats and mice are a natural nemesis for each other, the scent of cat urine can easily drive away the curiosity of a mouse far from your home. The best way to keep mice away is with used kitty litter so that the scent of urine will be apparent to mice, but not to you, your family, or house guests.
Make sure you purchase or use unscented kitty litter and begin to use this in your cat's box, if you do not already. In order for the mice to smell the cat urine, the kitty litter must not cover up the scent with perfumes and odor-block features.
Figure out where the mice are going the most often in your home and where they are entering or leaving. Keep and eye out for mouse droppings, which are small and dark ovals, and places they may have chewed. This can include the back of pantries or cabinets, vents, cracks under windows or doors, cracks in the foundation, wall corners, and other very small entrances. Once you understand where they regularly go, you can decide where to place the cat urine.
Put on the gloves. Use the scooper to remove kitty litter from your cat's litter box. Make sure that it is used kitty litter, where the cat has urinated. Collect a couple of large scoops (the size of a large handful) and insert them into a jar or container. Do not cover the container with a lid, so the smell isn't subdued.
Remember how many areas or entrances you found where the mice have apparently visited. With this number in mind, fill as many containers or jars as you need. So if you found mice droppings in a corner, by the patio door outside, and in the back of the pantry, put the used kitty litter into three different containers.
Place each of these containers holding the used cat urine by the designated mice areas and entrances. Keep the containers in these areas for two days, then dispose of the used litter and refill with a new batch. If you see new mice droppings occur in another area or entrance to your home, place a fresh container of the used kitty litter in this area. Covering every place you see evidence of mice will drive out the mice within two weeks, because it will become apparent to them that there is a regular predator in the area.
Keep a close eye on when the mice droppings completely stop within your household. Once you see this, remove all of the containers and dispose of. If you start to see mice droppings again, repeat this procedure.
Make sure that mice can't enter easily in the future by proofing your house. Seal all of the entryways mice might get in with extra padding or siding on your doors and windows and make sure to keep your house very clean.
