The dog and cat overpopulation problem is prevalent in many communities around the world, including the United States and Mexico, and a cross-border effort is underway for relief.

In Arizona, residents who travel to the leisure destination of Puerto PeƱasco, known as Rocky Point, are cooperating with their Mexican counterparts to try reducing the number of unwanted cats and dogs.

Tucson resident and University of Arizona student Krystin Sorich is a volunteer with the Animal Adoption Center of Rocky Point (ACORP), a non-profit organization founded in 2001.

Sorich attended a clinic in April at which volunteers from Arizona and Mexico altered 161 cats and dogs at the small clinic.

Spaying or neutering is "about a 10-minute process. It's very quick," Sorich says.

Another clinic is scheduled for November and Sorich says donations and volunteers will be vital.

"Personally just going down there and seeing the change in animals roaming the streets has been dramatic, actually," she says.
