The reasons why cats do not use litter boxes:
1. When a cat has a urinary tract or bladder infection, it will not be able to control its urine and feces, and it is necessary to take the cat to the pet hospital for examination and treatment in time. .

2. When the litter box is too dirty, the cat will not excrete in the litter box, and the owner needs to clean the litter box regularly.

3. When the location of the litter box is moved, the cat feels uncomfortable and will not excrete in the litter box.

4. If a new cat comes to the home and the cat is unwilling to share the litter box with other cats, it will excrete elsewhere and needs to buy another litter box.
5. If the cat does not like the litter because it smells too much or the particles are too large, it will not use the litter box and needs to be replaced with new litter.
