PHILADELPHIA (AP) — The sudden deaths of all five meerkats at the Philadelphia Zoo this month were apparently caused by an accidental poisoning linked to a dye that is used to mark the animals, zoo officials said, but an investigation into the deaths remains ongoing.

The meerkats — named Nkosi, Lula, Nya, Kgala, and Ari — came to the zoo as a group of siblings about a decade ago. The animals are gregarious and are known for their playfulness and communal living style.
