When an American woman took in two rats in the van she called her home, she had no idea it would end up with more than 300 of them.

With the rodents quickly multiplying, people started noticing them and eventually complained. To save her job, Carla contacted the San Diego Humane Society, and agreed to give them up.

Danee Cook, from the society’s law enforcement department, told San Diego Union-Tribune, "They could tell immediately that it was a huge amount (of rats). They were living out of the van, coming and going."

"This was not a cruelty case, this was relinquishment, an owner asking for help," she added. "She was feeding all of them, had water for all of them. This didn’t meet the standards of hoarding."

It took officers two days to find all of the rats and many were young and pregnant.

Almost 140 of them are already up for adoption in same-gender pairs.

A GoFundMe page was then set up to help Carla get a house. So far, more than $5000 have been raised for her.

According to the page, Carla moved into her van with two rats after becoming homeless.

Cook informed that the Humane Society Officers kept a check on Carla who has now found a place to stay. The rats have also been checked to make sure they are healthy and ready for their new homes.
