A sad, but hopeful update about the six red wolf pups born Friday at the Museum of Life and Science in Durham.During their first hands-on veterinary checkup this week, four of the endangered red wolf pups were found to be healthy. In the last few days, they’ve gained 20 percent to 35 percent of their body weight and are starting to make little squeaks.”They are robust and active with a strong sucking response and full bellies – all positive signs,” said Deborah Vanderford, attending veterinarian for the Museum of Life and Science, said in a press release.
