Catdoer

Catdoer sells automated litter boxes, modular climbing furniture, RFID feeders, and subscription-filter consumables. Most SKUs sit in the mid-range tier—$129–$399—with flagship self-cleaning units reaching $499. The brand is DTC-online only through catdoer.com and ships from U.S. and Asian warehouses. The company positions itself as the “open-source cat hardware” brand: all electronics use replaceable off-the-shelf parts and firmware updates are posted on GitHub. Its best-known product is the DoerBox Lite, a rake-style litter robot that can be disassembled with one screwdriver and runs on a $15 replaceable Arduino board. Every product page lists CAD files and printable repair pieces, a transparency move rare in the pet-tech space. Core buyers are millennial tech workers who already tinker with 3-D printers or home-automation hubs and want pet gear they can mod, fix, and integrate into Apple Home or Home Assistant. The brand appeals to values of sustainability, right-to-repair, and data ownership—users can opt to store litter-box usage stats locally instead of in the cloud. Catdoer competes with closed-system appliance-style pet brands that rely on proprietary cartridges and mail-in service. It differentiates by selling spare parts at cost, publishing repair videos, and coding firmware that lets owners disable features rather than replace the entire unit when sensors age.
