The staff at the Cherry Brook Zoo are mourning the loss of one of their animals—a Siberian tiger named Nyla.
The zoo saying in a release they were forced to euthanize the six year-old animal on Wednesday. 
After becoming suddenly ill on July 18, Nyla went blind, started having seizures and began losing weight—they
 consulted with other zoos and veterinarians from across Canada and the 
U.S., but she didn't respond to any treatments. The cause of death has 
been labelled a pneumonia.
As to whether or not they'll bring 
another tiger into the zoo, they say they're waiting on necropsy results
 first. They say they need to know what happened to Nyla before moving 
on.
The zoo says tigers can live into their twenties.
