Sonakshi Sinha is a professed animal lover, and she had posed for a PETA campaign advocating the adoption and sterilization of dogs and cats. She has starred in a one-minute video PSA, urging everyone to adopt animals and have them sterilised. She has been quoted saying “”Breeders, pet stores and people who don’t sterilize their animals are responsible for all the animals who end up homeless. Every time someone buys a dog or cat from a breeder or pet store, a homeless animal roaming the streets or waiting in an animal shelter loses a chance at a home and a good life.
