There may have been a few accidents and chewed-up baseballs during the shooting of a video for PetSmart's National Adoption Weekend at the Arizona Diamondbacks' Chase Field. But the cuteness overload made it all worthwhile.

The video was created to raise awareness for pet adoption and features former residents of the Arizona Humane Society — all of them now in their forever homes. PetSmart Charities holds national adoption weekends four times a year and says that each time, more than 15,000 pets nationwide find homes during those events. This weekend's event runs from today through May15.

PetSmart has created a season-long adoption center inside Chase Field, the first inside a Major League Baseball stadium.
