How many rats could you tolerate living with? The San Diego Humane Society said it got a call from a woman on October 8th from a woman who was living in a van near a convenience store in Del Mar, saying the number of rats under her care had gotten out of control. Officials arrived to find more than 300 rodents living inside the van, and they add that the woman was not hoarding the animals and it was not a case of cruelty. The owner says she initially had only two rats-- and officials say she agreed to turn over her pets-- many of which were juveniles or pregnant. The woman has since found a place to stay.
