Commercial pet mills produce puppies and kittens in factory-like conditions that cause severe welfare deprivation for breeding animals and their offspring.
Commercial pet breeding operations, commonly called puppy or kitten mills, prioritize production volume over animal welfare. Breeding animals are typically kept in wire cages for their entire reproductive lives with minimal veterinary care, no socialization, and no opportunity to engage in natural behaviors. The suffering of breeding animals in mills is chronic and severe. Puppies from mills have elevated rates of health and behavioral problems due to poor genetics and inadequate early socialization.
