What Lenderking Caging Products does

Lenderking Caging Products is a privately held, family-owned manufacturer of caging and housing solutions for laboratory research animals and the companion animal market, headquartered in Cambridge, Maryland. Founded in 1867 and operating continuously for 155+ years, the company designs and sells individually ventilated cages (IVCs), stainless steel kennels, thermo-neutral comfort cages, primate housing with proprietary vertical socialization features, transport units, and supporting facility carts and blowers. Its flagship Hygieia Ventilated Mouse Caging platform uses flow-through bedding technology at 30 ACH to enable 21-day cage change intervals, paired with the Air Sentry II Filter/Blower and web-based Argos monitoring software for remote rack management.

The company sells directly to contract research organizations, pharmaceutical companies, educational institutions, and government facilities (including NIH, a customer since the 1880s) on a quote-based, project-driven basis, with a consult-first sales motion and customization services for specialty applications such as telemetry and primate caging. Revenue derives from hardware sales plus custom design and consultation services, with one-time pricing (the Double Wide Comfort Cage for Rabbits starts at $8,000). Two sub-brands extend the platform: Comfort Kennels plus (pet care market, IBPSA member, Fear Free certified) and Lenderking Metal Products (industrial contract fabrication). Engineering talent is sourced from University of Maryland's Clark School and Johns Hopkins' Whiting School.

Multi-Species Kennels provide stainless steel options for dogs and larger animals.
