PUEBLO -- The Pueblo Zoo is investigating the unexpected death of a North American river otter pup.
Last week - Saga, a female pup - was discovered dead in the exhibit, according to the zoo.
A veterinary team took both tissue and blood samples and determined that the pup died from encephalitis, an acute inflammation of the brain.
They are working with a veterinary team at Colorado State University - Fort Collins to find the possible causes and future impacts.
As they monitor the otter family, they are "cautiously optimistic" that this is an isolated occurrence.
