What should I do if one cat attacks another cat in the litter box?

If one cat attacks another cat in the litter box, it is important to separate them immediately to prevent further harm. You can try to distract the aggressor cat with a loud noise or by gently spraying them with water. It may also be helpful to provide separate litter boxes for each cat to avoid future conflicts. If the aggression continues, it is recommended to seek advice from a veterinarian or animal behaviorist for further guidance.
