Pet snake ownership in the U.S. has surged, fueling a hidden industry of factory farms that breed reptiles and kill millions of feeder rodents.

This growth highlights a widening gap in animal welfare oversight as the demand for captive-bred snakes outpaces public awareness of the supply chain. The industry operates largely in the shadows, raising concerns about the treatment of both the reptiles and the rodents used as prey.

Data shows that the number of households owning at least one pet snake rose from approximately 810,000 in 2018 [1] to roughly 1.3 million in 2024 [1]. This increase is not only in the number of owners but also in the number of animals per home. The share of snake-owning households with more than three snakes doubled between 2018 and 2024 [1].

To meet this demand, undisclosed factory farms have scaled their operations. These facilities breed snakes for the pet trade and maintain vast populations of mice and rats to serve as food. Because snakes are carnivorous, the scale of the pet boom requires a corresponding increase in the production of feeder rodents.

The expansion of these farms has created an industrial-scale cycle of breeding and slaughter. While the pet trade often markets captive-bred snakes as an ethical alternative to wild-caught animals, the reliance on factory-farmed rodents introduces new animal-welfare challenges.

Industry participants have largely remained undisclosed, leaving the specifics of these operations out of the public eye. The rapid rise in ownership suggests that the infrastructure for breeding and feeding these animals has expanded faster than the regulatory frameworks designed to monitor animal care.

The shift toward captive-bred reptiles is intended to protect wild populations, but it has effectively transferred the ethical burden to a hidden agricultural sector. As the volume of feeder rodents increases to support millions of pets, the industry may face increased scrutiny regarding the welfare of prey animals, which typically receive fewer legal protections than traditional livestock.
