Petrust (officially Shenzhen Chongxin Technology Co., Ltd.) is a smart pet product manufacturer based in Shenzhen, China, specializing in self-scooping automatic cat litter boxes, smart pet feeders, and WiFi water fountains. We offer full OEM, ODM, and private label production. Pet brand owners, wholesalers, and Amazon/Shopify sellers are welcome to start a project with us.
An automatic cat litter box — also called a self-cleaning litter box —is a smart litter system that detects when a cat has finished using it, then runs a mechanical cleaning cycle to sift waste into a sealed drawer without manual scooping. It combines a rotating or raking mechanism, motion/weight sensors, and a sealed waste compartment to control odor and mess between cleanings.
Petrust’s automatic litter box lineup covers three core types:
Infrared, weight, and motion sensors each independently trigger an auto-pause — a cat re-entering mid-cycle never gets caught in the mechanism.
Private label self-cleaning litter boxes with your branding, App skin, and packaging — for sellers who need a defensible product, not a resold generic unit.
Bulk automatic litter box supply for multi-brand distribution, with consistent unit-to-unit quality across large purchase orders.
The process splits into three stages: structural molding, sensor/electronics integration, and full-cycle testing. Skipping the third stage is where cheap competitors cut corners — and where safety recalls come from.
Mass production typically takes 30-45 days after sample approval; repeat orders can be faster.
Choose EXW, FOB, CIF, or DDP terms based on your logistics setup; every shipment is quality-inspected and export-documented before dispatch.
A weight sensor and a sealed drawer alone don’t make a litter box “smart” — the real difference between a budget sifter and a premium self-cleaning unit is in the sensor stack, capacity, and odor-control system. Petrust supports three core types on the same safety architecture.
