Depending on who you ask, tending to the daily barrage of guinea pig needs can be either a fairy tale or a horror show. For Smothermon, it’s often a mix of both.

“If I could figure out how to get out of this at this point, I probably would,” Smothermon joked. “But I do believe that to a certain extent, I probably wouldn’t get out of bed if I didn’t have this.”

Smothermon is the owner of the Guinea Pig Sanctuary, in Salisbury, Massachusetts, roughly 40 miles (64 kilometers) north of Boston. On any given day, 350 to 400 guinea pigs are housed in a modest workspace, split into cages stacked from the floor to ceiling.

The space is cramped and chaotic as volunteers and visitors squeeze past each other between the rows of cages in a converted office space. People constantly move throughout the space cleaning out cages and checking on any sick animals.

But there’s also joy. The squeals from the little piggies about to eat lettuce and other vegetation often spark laughter, while others cuddle and comfort some of the guinea pigs. Each animal has a name prominently displayed outside their cage, as volunteers tick off their personalities.

Maui is friendly and gives kisses. Gritty is older, but shy. Rio has spunk and likes to run around. They all remember the smell of their caretakers and gravitate toward their favorites.

“They’re very sensitive animals,” said Janet Woodman, a volunteer at the nonprofit. “I personally think they are probably the best therapy animal next to a horse.”

Smothermon’s operation is one of the handful of animal rescues in the U.S. devoted solely to taking in abandoned guinea pigs — filling a need as people become overwhelmed with the responsibilities required to take care of these pets. The sanctuary additionally offers boarding for guinea pigs when their owners are traveling, as well as encouraging rehoming of the animals when they can.

Measuring between 8-10 inches (20.32-25.4 centimeters) long, these small beasts originally came from South America derived from the Cavia porcellus species, according to the Smithsonian’s National Zoo. After being domesticated in 5,000 B.C., there are now 13 different breeds that are distributed as both pets and for food.

According to Smothermon, guinea pigs often need to be adopted in pairs. They’re social and can’t be kept in cages full time.

Within minutes of opening the sanctuary earlier this year, an older woman walked through the door carrying two cages needing to “surrender” her guinea pigs. The woman’s husband had become sick, she explained to Smothermon, and she couldn’t properly take care of both him and her pets.

Smothermon hugged the woman and waived the usual fee.

“I tell people, just bring them here,” she said. “If that’s what you need to do, I’ll take on the responsibility.”

Other days, Smothermon is fielding calls from across the U.S., asking if she can take 11 piggies from Illinois, seven from Texas, and 97 from New York — where nearly half are expected to have babies.

It’s a constant stress that Smothermon never imagined would consume her life. It initially began when her grandson, Alex, brought home a guinea pig. Alex had fallen into a fire as a child and experienced health problems, causing him to avoid most animals up until he was 12, when he discovered it was safe to interact with guinea pigs.

From there, Smothermon said, her family became a resource to take in abandoned guinea pigs. The family ran the rescue out of their New Hampshire house until a fatal fire burned it down in 2019. The fire resulted in the loss of Smothermon’s other grandson, two dogs and dozens of guinea pigs.

The tragedy sent Smothermon into a depression, but when her family was living out of a hotel as they looked for a new home, people still kept dropping off guinea pigs that needed help.

Seeing the need gave Smothermon and her family the focus and motivation to continue Alex’s dream, and eventually they relocated to Massachusetts.

Smothermon says the work is hard. She only gets a handful of days off a year, but the constant drumbeat of needing to take care of hundreds, if not thousands, of guinea pigs keeps her grounded.

“If I don’t get up, they don’t eat and they can die. So even though it’s not a choice, I have to,” she said.
