Arizona Humane Society sounds alarm on growing pet crisis

The Arizona Humane Society is warning of a worsening pet overpopulation crisis after taking in more than 25,000 dogs and cats in 2025, its highest intake in more than a decade.

AHS leaders say the number could rise to 28,000 animals this year without urgent action.

In response, Valley philanthropist Ann Siner, the CEO of My Sister’s Attic, has pledged $600,000 to launch a major spay and neuter initiative.

“The reality is that we cannot adopt our way out of this crisis,” Siner said in a Thursday news release.

Siner is calling on Arizonans to contribute. She will match donations of $1,000 or more, dollar for dollar, until her matching pledge reaches $600,000.

Why is Arizona’s pet overpopulation crisis so bad?

The surge is part of a broader national shelter crisis tied to several factors, including irresponsible breeding practices and rising veterinary costs.

“The only true solution is spay and neuter,” Siner said. “If these numbers continue to rise unchecked, more pets across Arizona will face euthanasia simply because there is nowhere for them to go.”

Shelter officials say the pause in routine sterilization procedures in 2020 created a ripple effect that continues to strain shelters.

“It breaks my heart to see so many pets in need with nowhere to go, so I decided to give $600,000 and challenge people in Arizona to step up and help,” said Siner. “Please donate. Every dollar helps, even $50.”

Those who want to help fight Arizona’s pet overpopulation crisis can donate online or call 602-997-7585 and pick Option 4 to give.
