Funnyman Ricky Gervais has posed for a photoshoot with his beloved pet cat to back an animal rights campaign.

The Office creator has thrown his weight behind the British Union for the Abolition of Vivisection's Our Best Friends drive, which calls for officials in the U.K. to end the use of cats and dogs in lab experiments.

In his photo for the campaign, Gervais is seen smiling with delight as he reclines on a sofa with his black and white feline Ollie.

The actor/comedian says, "Cats share our homes, they are loving, loyal and playful and they deserve a safe and happy life, not one of suffering. That's why I am supporting the Our Best Friends campaign, taking action to bring a stop to the suffering of cats and dogs in U.K. laboratories. Take a look at ourbestfriends.org and sign the petition today at ourbestfriends.org/petition."
