In a significant rescue operation this week, Pasadena Humane saved close to 100 small animals from a single Arcadia residence, marking it as one of the most substantial small-animal hoarding incidents the shelter has dealt with recently.

The rescue involved the relocation of 31 mice and 63 hamsters. Notably, some of these hamsters are pregnant, and officials anticipate the total number of animals could soon surpass 100 once the new litters arrive, according to a Thursday statement from the organization.

Following the rescue, each animal received thorough veterinary examinations, suitable housing, and continuous care, as stated by shelter representatives. While all the animals were generally found to be in good health, one hamster was discovered with a minor leg injury. Pasadena Humane assured that the cause of the injury remains unknown but the hamster is on track for a swift and complete recovery.

The rapid reproductive capabilities of mice and hamsters mean that without proper separation, a few pairs can quickly multiply into dozens. Fortunately, these animals are now under proper care and attention, mitigating the risks of unchecked population growth, the shelter emphasized.

Pasadena Humane has temporarily converted one of its communal cat rooms to house the animals and is now seeking adopters to give them new homes. Adoption fees are $10 for mice and $15 for hamsters, with a limit of four of the same sex per household.

Adoptions are available daily from 10 a.m. to 5 p.m. at Pasadena Humane, 361 S. Raymond Ave. in Pasadena. Adoptable pets can also be viewed online at pasadenahumane.org.
