Twitter cofounders Biz Stone and Evan Williams are putting their money where their beaks are, backing Beyond Meat, a company that produces cruelty-free faux meats. Now, every time cruel meat-peddling companies such as McDonald's use Twitter, they'll actually be helping to support the vegan cause!

Tricia Helfer is tweeting to help end the Canadian seal slaughter and wearing her PETA pride on her sleeve chest:

After rescuing a dog himself, Josh Duhamel is a proud rescue advocate: "Pet adoption changed my life when we were looking to find a companion for our 7-year-old dachshund, Zoe. Soon after adopting Meatloaf, I learned that these pets are just grateful for the love you have to give them."

Yvonne Strahovski will be taking her animal rights advocacy to a killer new venue, as she will be appearing on season seven of Dexter, and Waka Flocka Flame's new album, Triple F Life, which debuted this week, is decidedly free of one "f" ("fur") and full of another ("fun").

Quite a few longtime PETA friends and faves were among the celebs who told the Associated Press about their animal-oriented New Year's resolutions, including Bob Barker ("To continue urging folks to have their pets spayed and neutered—including rabbits."), Lea Michele ("I wish that [my cat] Sheila would stop going into my bathroom, taking out all my cotton balls out of the jars and spreading them all over."), and Katherine Heigl (whose dogs want her "to feed them consistently on time in the morning"), not to mention superhot Josh Duhamel and music legend Roberta Flack, whom we love all the more after hearing about their rescued animal friends.

Other pro-adoption superstars? How about George Clooney, who recently talked to Esquire about adopting his shelter mutt, Einstein? Or Charlize Theron, who wants more people to, well, be like George?

If anyone you know needs convincing that tofu scramble is the real breakfast of champions, you can remind him or her that vegan WWE superstar Daniel Bryan has been awarded the world heavyweight title. Then break a chair across his or her back just to get the point across. (PETA's lawyers would like us to note that this is a joke and that violence is never the answer.)

Not to be outdone, the UFC took to Twitter to urge fans to vote for Jake Shields for peta2's Most Animal-Friendly Athlete Libby Award.

A number of other stars offered up pro-animal tweets as well:

And the always amazing Oscar-winner and Raising Hope star Cloris Leachman raised some hope for animals abused in circuses by writing to the mayor of Orlando and asking him to protect the elephants scheduled to perform in the city with Ringling Bros.
