Non-profit Matches Greyhounds With Families

In 1991, when Dennis Tyler adopted a former racing Greyhound named Clara Voyant, he had no idea how much she would change his life. But when he learned how many Greyhounds face the risk of injury and euthanization, he knew he had to do something. So he and his wife started Florida Greyhounds, a non-profit that provides medical care for the racing dogs as well as matching them with compatible families. The organization has since found homes for more than 7,400 greyhounds. "These dogs can be the most wonderful pets," Tyler told People magazine. — Read it at People

Sheep Dogs Protect Penguins on Middle Island

When the population of Little Penguins on Australia’s Middle Island dropped to fewer than 10 birds — down from 700 in the ’90s — the city council wasn’t sure what to do. That’s when David Williams, an environmental science student working part-time at a free-range egg farm, suggested placing Maremma sheepdogs — the same dogs his employer used to guard the chickens — on Middle Island to protect the birds from their greatest predator, the red fox. And it worked. Seven years later, the penguin numbers are back in the hundreds, and two sheepdogs continue to keep watch over their “flock.” — Read it at Huffington Post

130 Cats in Daytona Need Homes

Whales break free from ice

Orcas Free Themselves From Icy Waters

A dozen distressed killer whales in the frozen waters of Canada’s Hudson Bay appear to have finally broken free on Thursday, to the relief of the thousands that had been keeping tabs on their plight. The orcas had been stuck underneath the ice and had only a 10-foot opening to surface and breathe. They took turns bobbing up through the hole in the ice and caught the notice of locals, who ramped up rescue efforts for the whales. Experts say climate change is to blame for the cracked sea ice that trapped the animals. — Read it at NPR
