HSSA Accepts 45 Cats and Kittens in Large-Scale Transfers Across the Southwest 

Regional capacity and medical facilities position HSSA as a resource for animals in need across the Southwest. 

WHAT: 

The Humane Society of Southern Arizona (HSSA) accepted 45 cats and kittens in a large-scale animal transfer from partner organizations in Pinal County and Riverside County, California. 

WHO: 

Humane Society of Southern Arizona 

Dr. Karyn Carlson, Chief Veterinary Officer 

DETAILS: 

The incoming animals included: 

•25 kittens from Pinal County 

•19 cats and kittens from Riverside County, California

HSSA’s medical team, on-site veterinary clinic, and experienced shelter operations staff were on site to receive, assess, and care for the incoming transfer early on June 25 for one of the largest transfer days in the organization's recent history. Established intake protocols ensured the health and safety of both incoming animals and existing residents throughout the process. HSSA CEO Dr. Kristin Barney, who joined the organization in 2024, and Chief Veterinary Officer Dr. Karyn Carlson, who joined in 2025, were also on site supervising the transfer. 

Once cleared and provided spay/neuter surgeries and other necessary medical care, the animals will be moved into HSSA’s adoption and foster programs, where staff and volunteers will work to find each pet a loving home.  

Transfers like this one are made possible in part by the success of HSSA’s Trap-Neuter-Return (TNR) efforts in Southern Arizona, which have helped stabilize local cat populations and freed up capacity for HSSA to support partner communities in need. HSSA’s Community Cat Program is widely recognized throughout the national animal welfare community as a model for humanely and effectively managing community cat populations.  

HSSA also remains in close contact with Pima Animal Care Center and stands ready to support dog transfers as their needs develop. 

"We were in desperate need of help getting cats adopted,” said Audra Michael, Director of Pinal County Animal Care and Control. “They were coming in faster than we could house them. The Humane Society of Southern Arizona came to the rescue and took nearly our whole cat room, which was just incredible.”  

STATEMENT FROM KAITLYN PAPPAS, SENIOR SHELTER MANAGER: 

“Yesterday was a big day for our team. There were over 40 cats and kittens through the door in a single day. The animals were diverse in medical needs, breeds, and age. We immediately clocked some of their personalities as the braver ones demanded food, unappreciative of the lack of in-flight entertainment and food service  on the trip from California. They are all so adorable and settling in, and we can’t wait to get them into loving homes.” 

STATEMENT FROM DR. KARYN CARLSON, CHIEF VETERINARY OFFICER: 

"Our medical team was ready for whatever those animals needed, from the routine intake exams we conducted to more immediate medical care. I am so proud of this organization’s investment in top-of-the-line medical facilities, such as the brand new Max’s MASH Unit. That dedication to life-saving services at HSSA is exactly how we can accommodate so many pets at once during intake.”
