- Working with actor and rescue cat mom - Shailene Woodley - Mars and Calm are shining a light on the positive impact of pets on mental wellbeing, and how adopting a pet can change two lives - the pet's and pet owner's.
- A recent global survey commissioned by Mars and Calm found a huge 83% of pet owners say their pet has improved their mental wellbeing.1
- With an estimated 12 million dogs and 4 million cats living in shelters across the globe waiting to meet their forever family, Mars, Calm and Shailene are coming together to promote pet adoption and the power of the human animal bond ahead of the Mars Global Adoption Weekend (October 3-5, 2025).
BRUSSELS, Sept. 30, 2025 /PRNewswire/ -- Mars, a leading pet care company behind brands pets and pet owners love including ROYAL CANIN®, WHISKAS®, CESAR®, BANFIELD, BLUEPEARL, VCA and ANTECH®, is teaming up with award-winning actor Shailene Woodley ("Motor City", "Paradise", "Big Little Lies") and leading mental health company Calm to shine a light on the power of pets for mental wellbeing and to encourage adoption as a path to pet ownership.
Globally, there are around 16 million dogs and cats in shelters waiting to find a home.2 In an effort to help pets in shelters find loving homes, Mars is hosting its second annual Global Adoption Weekend. For those who open their homes to pets, the rewards are huge. The bond with a pet has a measurable, positive impact on mental wellbeing. A recent global survey commissioned by Mars and Calm found a huge 83% of pet owners say their pet has improved their mental wellbeing, and 73% say their pet encourages them to stop overthinking or worrying.1
Shailene Woodley said:"My rescue cats transformed my world. They bring me peace when I'm overwhelmed with a busy filming schedule, and every day, they remind me to breathe, slow down and live in the moment. I want more people to see that adoption isn't just an act of compassion for an animal; it can also be an act of care for yourself. In rescuing Bear and Pharrah, they have changed my life as much as I have changed theirs."
Spending time with pets has also been found to increase levels of oxytocin, dopamine, and serotonin, collectively known as the 'happy hormones' because they promote a sense of wellbeing and contentment.3 Plus, the benefits go both ways as studies have found that in three months of adoption, dogs show signs of increased confidence and cats show signs of bonding and calmness.4
"Our increased understanding of the human animal bond and how it can impact mental wellbeing highlights the unique relationship between people and their pets," Dr. Alea Harrison, DVM; Chief Medical Officer at Banfield, commented. "The first days with a new pet are key to learning about each other. Strong bonds are built slowly, through patience, consistency, and care - and when they take root, they can bring joy, companionship and fulfilment."
During the Global Adoption Weekend Mars will be supporting prospective pet owners through partnerships with shelters, helping change two lives by bringing more pets and people together across more than 20 countries, incl. U.S., U.K., Australia, Austria, Belgium, Brazil, Canada, Czech Republic, France, Germany, Greece, Hungary, Ireland, Italy, India, Japan, Mexico, Spain, Switzerland, The Philippines, Poland, Romania, Thailand, and Ukraine.
Tiffany Lacey, Executive Director of Animal Haven, one of the shelters that are part of the Global Adoption Weekend in the U.S., said: "With millions of pets waiting for their forever home, adoption is a tangible way to make a lasting difference - and Mars Global Adoption Weekend is the perfect time to visit your local shelter. Every adoption is proof that compassion changes lives, giving pets a loving home and enriching the wellbeing of the people who welcome them."
Mars will be promoting adoption through a range of initiatives from financial contributions to shelters, local events and associate volunteering. This includes:
- In the U.S., Mars will cover more than $185,000 in cat and dog adoption fees at partner shelters in 21 cities during October 3-5. On top of that, the PEDIGREE Foundation will cover an additional $25,000 in dog adoption fees.
- In Poland, Mars will support new pet owners by providing them with a 6-month supply of pet food for cats and dogs adopted from partner shelters.
- In The Philippines, Mars will donate 33,000 meals for pets in partner shelters, making a positive impact for pets in need across the community.
- During the month of October, Mars and Calm are also supporting adoptive pet owners as they settle into pet ownership by providing them with 3 months of free Calm membership.
As part of the campaign, Shailene has recorded a Sleep Story, exclusively available on Calm, inspired by her own experience welcoming pets into her life and other amazing stories of four-legged friends changing the lives of those around them. The Sleep Story, Finding Four-Legged Friends, is part of the first-ever pet-inspired content collection on Calm created in collaboration with Mars, and it also features free-to-access content (incl. meditations, breathing exercise, soundscapes and more), to help pet owners find calm and rest.
