To celebrate our 15th annual Adoption Weekend, this year we’re hosting our biggest adoption event yet, covering adoption fees in 15 U.S. cities including Nashville, Los Angeles, Chicago, Phoenix and more.
About Adoption Weekend 2023
The 2023 Mars Pet Adoption Weekend runs from Friday, September 29, through Sunday, October 1.
Mars and its family of Petcare brands including ROYAL CANIN® and Camp Bow Wow® will cover up to $100,000 in cat and dog adoption fees at partner shelter locations in across the U.S. to help drive adoptions and further our global ambition to end pet homelessness. PEDIGREE Foundation will also cover up to $50,000 in dog adoption fees in select Adoption Weekend markets.
Each adopted pet will go home with a Mars Petcare starter kit. Depending on the location, this may include food and treats from brands like PEDIGREE®, IAMS™, ROYAL CANIN®, DENTASTIX™ or TEMPTATIONS™; an opportunity for a complimentary health exam from VCA Animal Hospitals or Banfield Pet Hospital®; a free day of day care from Camp Bow Wow® after successful completion of a dog’s interview day; and coupons and swag from Camp Bow Wow®, VCA Animal Hospitals, WISDOM PANEL™ DNA Test, WHISTLE™ and the BETTER CITIES FOR PETS™ program.

Why Adopt?
Despite a growing awareness of the many benefits pets bring, from companionship to increased wellbeing, more than six million pets enter U.S. shelters each year.1 Even as interest in pet adoption has risen, the number of stray pets arriving at shelters has increased 26% since 2021.2
When you adopt, you give a pet a loving home and help free up space at the shelter for other pets in need.
Need more convincing? Surveys show that people report feeling more relaxed and happier when they’re with a pet, that pets help reduce loneliness, and that pet ownership helps promote strong communities.
Check out this list of eight great reasons to adopt a dog or cat.
While we hope many people across the country will take part in the 15th annual Mars Pet Adoption Weekend, supporting pets is a year-round need. Please consider volunteering, adopting or fostering at a shelter near you!
