Meerkat deaths at Philadelphia Zoo linked to suspected poisoning.

TL;DR
All five meerkats at Philadelphia Zoo have died within a month, with officials suspecting that they may have accidentally consumed a toxic dye used to mark them. The dye, Nyanzol-D, is thought to be the culprit. A necropsy is pending, and the zoo is coordinating with the US Department of Agriculture and the Association of Zoos and Aquarium to identify the cause of the deaths. The zoo currently houses more than 1,900 animals.
