It's official: Oprah will end her show in 2011. Feel that collective surge of sadness? We sure do. Oprah's groundbreaking program has transcended the talk-show format and has paved the way for social and political change. In honor of PETA's 2008 Person of the Year and her show's long run, we're revisiting Oprah's best animal-friendly episodes:

• Oprah's week-long move from Chicago to Amarillo was the move followed 'round the world. She captivated millions with her court appearance to defend her 1995 episode that revealed the horrors of a beef industry rampant with mad cow disease.
• Inspired by guest Kathy Freston's book Quantum Wellness, Oprah went vegan for three weeks and marveled, "I never imagined meatless meals could be so satisfying."
• Oprah dedicated an entire episode to exposing the stifling, crippling conditions of chickens, cows, and pigs on factory farms as Californians prepared to vote on Proposition 2. The measure passed by a large majority—in part thanks to her revealing show.
• After Oprah saw a billboard off the Kennedy Expressway that read, "Oprah: Do a show on puppy mills. The dogs need you," she immediately jumped at the opportunity to save lives. Just a few minutes of her horrifying exposé were enough to convince viewers that adopting from an animal shelter is the only way to go.
• My food envy was raging when Chef Tal Ronnen cooked his "Chicken" Scallopini and other delectable vegan meals on a recent episode of the show.
• When Charla Nash decided to show her face to the public for the first time earlier this month, it's no surprise that she chose to do it on Oprah's show.

The media mogul may be bidding farewell to her legendary talk show, but with the upcoming launch of her new cable network, we're sure that we'll be seeing a lot more of her for a long time to come.

Earlier this year, Travis, a 15-year-old "pet" chimpanzee, was stabbed repeatedly, pounded with a shovel, and finally shot to death after he attacked a Connecticut woman named Charla Nash. Yesterday, Ms. Nash, who has been in a hospital since the attack, appeared on The Oprah Winfrey Show and spoke for the first time about her recovery. During the show, Nash declared her readiness to move on and said that she had an optimistic outlook on the future.

The images of Nash are shocking, her buoyant hopefulness is inspiring, and both of those points should prompt another look at Travis' trajectory from his days as a baby chimpanzee to his years as a confined adult "pet." Travis, who appeared in several commercials when he was an infant, was just one of many exotic animals who have been torn away from their mothers at a young age in order to be raised by people who don't fully understand their needs.

Once chimpanzees reach adolescence, they become too strong and aggressive for their guardians to handle. They are then often abandoned at roadside zoos or—as was the case with Travis—stay in the home of a person who remains unaware of their tremendous strength until it's too late.

Chimpanzees and other exotic animals were never meant to be confined to people's homes, and keeping them as "pets" can often be lethal to both the animals and those who live near them.
