Buying Guide for Smart Litter Boxes with Wide Entry

Entry Width and Height

The most important factor is the size of the opening. A wide, low-entry design allows cats of all ages and sizes to enter without jumping or squeezing. Look for boxes with a step or platform for added stability. The Meowant 75L model, for example, offers a low 6.8-inch step, making it ideal for short-legged, senior, or plus-sized cats. Similar considerations apply if you have larger felines, as discussed in our best smart litter boxes for big cats guide.

Safety Sensors

Smart litter boxes must have reliable sensors to pause operation when your cat approaches. Weight sensors, infrared sensors, and anti-pinch mechanisms are essential. The Thereye model features an 11-point safety system including radar and Hall sensors. This ensures your cat is never at risk during cleaning cycles.

Odor Control

An effective odor control system keeps your home fresh. Look for sealed waste bins, built-in deodorizers, and self-sealing bags. The Ellenpent model uses a dual-defense system with leak-proof construction and deodorizer gel, while the Thereye adds a drawstring closure for hands-free sealing. If you have multiple cats, managing odors becomes even more important; see our best smart litter boxes for multiple indoor cats for further insights.

Smart Features

App control lets you monitor usage, set cleaning schedules, and receive alerts. Most models require 2.4GHz Wi-Fi. The ABRCT and HHOLOVE boxes offer app connectivity with health tracking, while the Thereye allows remote adjustment of drum height. These features help you stay informed about your cat’s bathroom habits, even when you are away from home.
