The Humane Society of Southern Arizona currently has more than 300 animals in its care, and is taking in numerous litters every day.

To free up space for the flood of kittens and puppies that come every year, the HSSA is offering half-off adoption fees for all cats 5 months and older and all mixed-breed dogs 5 months and older and 25 pounds and over at all locations.

Each dog or cat will go home microchipped, vaccinated, vetted and spayed or neutered.

Adoption specials start today and last through Sunday at all locations, including the main shelter at 3450 N. Kelvin Blvd., PAWSH at Park Place and La Encantada and Petsmart on River and Orange Grove Road.
