## Description

Made from polypropylene (PP), the UPFAS CAST-LB500C is an automatic litter box designed for medium cats and kittens weighing 3.5 to 15 pounds. Its silver-gray finish and 22.44 x 18.23 x 19.84-inch footprint make it a defined station for your cat’s routine.

App control adds a way to follow litter box activity from your phone. Connect through 2.4GHz Wi-Fi or Bluetooth to view weight, time spent, and frequency of use.

The unit requires assembly, which takes approximately 30 minutes. Reviewing the user manual and assembly video beforehand can help you plan setup.

## Everyday use

The CAST-LB500C is intended to clean itself automatically, giving cat owners an alternative to a basic litter box that needs manual scooping. In a home where you want to keep tabs on litter box habits, the app’s usage history can show weight and visit patterns alongside the cleaning function. What does that look like in practice? You can check the recorded activity through the app rather than relying only on visual checks of the litter area.

Its operation is specified at below 35 dB, a useful detail for a litter box placed in a lived-in part of the home. For routine upkeep, the drum lifts out for cleaning and is washable with water. Place the unit where your cat can access it comfortably, and follow the assembly instructions before use.

## Pros

The main advantage is the combination of automatic cleaning and app-based activity tracking. It suits households looking to move beyond a standard tray while keeping information about their cat’s litter box use accessible. Weight monitoring and usage history add practical context for following routines, while the quiet-operation specification supports use in a shared living space.

Buyer feedback commonly highlights quiet operation, straightforward setup, and cats taking to the box. Some buyers also describe it as easy to clean. Experiences with odor control are mixed, so the documented benefit to focus on is the automatic cleaning process rather than an assured odor outcome.

## Key features

The model is sized for medium cats and kittens in the stated 3.5-to-15-pound range. Its dimensions are 22.44 inches long, 18.23 inches wide, and 19.84 inches high, with a product weight of 23 pounds. The body is made of polypropylene (PP), and the listed color is silver gray.

App connectivity supports 2.4GHz Wi-Fi or Bluetooth. The app provides real-time health monitoring and usage history, including weight, time spent, and frequency of use. Automatic cleaning, quiet operation below 35 dB, and a lift-out drum that can be washed with water bring the core functions together in one unit. Assembly is required and takes approximately 30 minutes.

## Should you buy it?

Choose the UPFAS CAST-LB500C if you want an automatic litter box for a medium cat or kitten and value app access to weight and usage patterns as part of everyday care. Its self-cleaning design, quiet-operation specification, and washable drum make it a practical option for replacing a basic tray with a more automated setup.
