Lenderking

Lenderking, America’s oldest caging company, specializes in designing durable, animal-friendly research and veterinary enclosures that promote natural behaviors while meeting user needs.

Founded in 1867 by Phillip H. Lenderking, the company has evolved from metal roofing and plumbing into a leading family-owned and operated manufacturer of research animal housing solutions. With over 150 years of experience, Lenderking combines innovative, durable enclosure designs—such as the Hygieia ventilated mouse cage, which extends safe cage change intervals up to 21 days using less than half the airflow of conventional systems—with flexible, customizable services for institutions across commercial, industrial, pharmaceutical, governmental, and educational sectors. Their commitment to animal welfare and practical usability underscores their enduring reputation.
