The San Diego Humane Society and SPCA noted the largest animal rescue in their history – 420 chinchillas taken from a ranch in Vista.

The eight-hour chinchilla rescue that took place Tuesday was prompted by People for the Ethical Treatment of Animals, according to the Humane Society.

“We received a request from PETA to rescue and care for the chinchillas from a Vista-based business they procured,” said Dr. Gary Weitzman, president and CEO of San Diego Humane Society. “Every animal matters, and we take our responsibility to care for and protect all animals in our community.”

PETA said that the chinchillas that weren’t purchased as pets were electrocuted and in undercover video was told how the process took place and how a bit of brandy was used to sedate the animals to have limbs removed.

Their pelts were removed and put up for sale at the Vista farm, according to the organization.

Upon arrival at the San Diego Humane Society, the animals taken in the chinchilla rescue were examined by veterinarians and animal welfare professionals.

Special veterinary care, housing enclosures, food and medical supplies and space are necessary to care for the large volume of animals, according to the Humane Society.

“We weren’t necessarily expecting 400 chinchillas on top of the nearly 2,000 animals we’re already caring for, but it’s our mission to help all animals who need us,” Weitzman said.

The chinchillas will be put up for adoption after they’re determined to be healthy. The Humane Society said the animals will also be provided any necessary “behavior modification” before they are allowed to be given to families.

Chinchillas are rodents native to South America, and are listed as “a critically endangered species.” They but have become popular pets in recent years. Similar to guinea pigs and rabbits, chinchillas can be sweet, social and trainable, according to the Humane Society.
