Most kittens will instinctively use a litter box with little or no actual training effort. Simply place your kitten in the box and make sure it is always accessible to the kitten.
If your kitten has trouble learning to use the litter box try closing your kitten in a small room or crate with a litter box until it has a better understanding of what a litter box it. Once your kitten is better at using the box, then you can allow your kitten more freedom.
Make sure your cat can easily get to and into the litter box. This is especially important with kittens and senior cats.
Cats use urine and feces as a way to mark and leave messages for one another. In multi-cat households it is not uncommon for at least 1 cat to eliminate outside of the litter box at least occasionally. To decrease the likelihood, try the following:
- Provide at least one more litter box than the number of cats in the household.
- Clean/scoop solids from the box at least once daily.
