From an email I just received from Leilani Farm Sanctuary:
"As the pandemic recedes and kids return to school, parents are surrendering guinea pigs to the humane society in record numbers. To combat this problem, we have asked Petco to stop selling guinea pigs purchased from breeders. We are communicating with Petco's corporate office and have invited the local manager to visit the Sanctuary.
The overpopulation of homeless guinea pigs on the island prompted the Maui Humane Society to ask us to take in sixteen new guinea pigs. "
