Bollywood actor and reality TV star Sunny Leone appears in the latest advert from People for the Ethical Treatment of Animals (PETA) India.

Leone, who is appearing in Jism 2 wants her fans to know that the only way to fight the worldwide animal homelessness crisis is always to have companion animals sterilised.

In an interview for PETA India, Leone said, "I believe in not buying – and adopting. And it's because there's so many dogs out there that need a home, that were left on the streets. … They just need that love, and if you can rescue an animal, then that's one of the greatest gifts you can give somebody".

"I believe that every single dog should be spayed and neutered. You don't want to continue the cycle of homeless dogs or cats.

And spaying and neutering also keeps them healthy. It prevents them from having different diseases that they can get if they are not". PETA India's exclusive broadcast-quality interview with Leone is available for download here.

Thousands of unwanted cats and dogs enter animal shelters every year in the UK, and many of them are euthanised because there simply aren't enough good homes for them.

Many more never even make it to an animal shelter – they are abandoned to fend for themselves on the streets and are often subjected to cruelty or succumb to starvation, disease or injuries. The only answer is prevention through always spaying and neutering your animal companions. Spaying one female dog can prevent 67,000 births in six years, and spaying one female cat can prevent 370,000 births in seven years.

Leone, who shares her home in Los Angeles with two rescued dogs, has also signed on to star in the sequel to the horror-thriller film Ragini MMS, one of the most talked about sleeper hits of 2011. The makers of Jism 2 have donated the film's wardrobe, including sexy lingerie worn by Leone, to PETA India for auction.
