One of the many wonderful things about cats is that they’re not difficult to house train. A cat’s natural instinct is to relieve itself in sand or soil, so after you’ve introduced a cat to its litter box a few times, it will instinctively use the box to relieve itself from then on. On the other hand, choosing the right litter box is difficult, especially with the growing range of luxurious litter boxes available on the market today.
