Pasadena Humane Responds to Largest Small Animal Hoarding Case in Recent History

Pasadena Humane has impounded more than 90 small animals following a hoarding case in Arcadia, marking the largest such intake in the shelter’s recent history. The nonprofit reported receiving 31 mice and 63 hamsters, some of which are pregnant and expected to give birth in the coming days. The total number of rescued animals is currently 94 but anticipated to exceed 100 due to expected litters.

The animals were transported to Pasadena Humane’s shelter, where staff conducted veterinary exams, provided appropriate housing, and ensured ongoing safekeeping. All but one hamster were found to be in good health. That hamster is being treated for scabbing and minor swelling in its left hind leg. The cause of the wound is unknown, but the animal is expected to make a full recovery, according to a statement issued by Pasadena Humane on Thursday.

Chris Ramon, president and CEO of Pasadena Humane, said the shelter acted swiftly to stabilize the animals and is now seeking adopters.

“Thankfully, these critters are now safe and receiving the attention they need,” Ramon said. “Now, we’re hoping our community can open their hearts and homes to help us find loving placements for each and every one of them.”

The shelter noted that small animals such as hamsters and mice breed frequently — sometimes producing new litters every few weeks — and unseparated pairs can quickly multiply into dozens, contributing to hoarding conditions.

All rescued animals are available for adoption at Pasadena Humane’s campus. Adoption fees are $10 for mice and $15 for hamsters, with a limit of four animals of the same sex per household. Adoption counselors are on hand to provide potential adopters with information and guidance on proper critter care. Animals can be viewed online at pasadenahumane.org or in person during adoption hours.

Founded in 1903, Pasadena Humane operates as a community-supported animal resource center serving the Greater Los Angeles Area. In addition to pet adoptions and foster care, the organization offers programs aimed at helping people care for and keep their pets, including free and low-cost spay/neuter and vaccines, a pet food pantry, and an animal support call center.

In 2024, Pasadena Humane assisted nearly 55,000 animals through adoptions, wildlife rehabilitation, lost and found services, veterinary care, and surrender prevention.
