Sienna Spiro is lending her voice to a PETA UK campaign encouraging people to adopt animals from shelters rather than buy them from breeders or pet shops. As part of the campaign, Spiro visited the Mayhew animal welfare organization and spent time with rescue animals waiting for permanent homes. The campaign also draws attention to the wider adopt, don’t shop message promoted by animal welfare groups. Its focus is on giving shelter animals another chance while reminding prospective owners that pets require ongoing care, time, and attention. For Spiro, the message is simple: people looking for a companion animal can make adoption their first option.
