Cat litter may be bought in bulk, packaged in reusable plastic storage-buckets.
Cats naturally repel mice from your home. They are cleanliness-loving creatures who like to clean up after themselves, and resist things that are dirty, unlike dogs.
Cats can be left alone in your dwelling for days at a time, provided with dry food and water dispensers (they emit the food or water gradually from a plastic storage bin), and a couple of cat-boxes. Technological geniuses have developed litter-boxes that are self-cleaning.
Cats will sleep most of the time while you aren’t home, and will amuse themselves for a few minutes a day to get their exercise.
