Something Squirrelly this Way Comes

Sad news on this holiday. Two silverback gorillas at the National Zoo have died within three days of each other. First one died during open heart surgery and the second one died two days later of heart disease.

Apparently heart disease is the leading killer in captive gorillas. It's not known if gorillas in the wild have the same problem as they don't typically live as long. At least, that's what the news was saying.
