It typically contains a lever or button that an animal can press to receive a reward, such as food or water.

Some self-cleaning litter boxes also have a timed cleaning cycle or can be manually activated by the pet owner. This helps to keep the litter box clean and odor-free without the need for frequent manual scooping. **
