About Us


Welcome to the Humane Society of North Iowa! 

Our organization was founded over 50 years ago with the mission to provide temporary shelter, food, medical attention, and comfort to displaced and neglected companion animals and educate the public about the humane care of animals with a goal of reducing overpopulation.

The heart of our mission is the operation of our newly constructed pet adoption center in Mason City, IA.

There are many ways you can be a part of our mission; Volunteering, donating, foster care, and animal socializing are just a few of the many ways you can show your support for the Humane Society of North Iowa.

Our new 6600 square foot facility houses almost 100 displaced, unwanted, and stray animals all looking for new homes.

We hope you will come visit us soon!

Adopting A Friend

The Humane Society of North Iowa adopts hundreds of animals each year to loving, qualified homes.  To adopt an animal from us, you are asked to submit an Adoption Application. (get it at the shelter or on the “Application Forms” page)
Adoption fee covers the following veterinarian services: spay/neuter surgery, rabies vaccination, flea and wormer treatment, feline leukemia test in cats, heartworm test for dogs.
Adoption Fees:


Kittens (under 1 year):                    $115.00
Adult Cats:                                       $105.00
Senior Cats (over 10 years):           $  90.00


Puppies (under 6 months):                $175.00
Adult & Puppies (over 6 months):     $150.00
Senior Dogs (over 7 years):               $110.00

Have you found an animal you would like make your new best friend?  GREAT!  The next step is to fill out an Adoption Application.  

We don’t operate on a “first come, first serve” basis.  Every new animal will spend several days in our shelter so that families and individuals can have the chance to submit an application if interested.  We then review all applications and select the home that will best fit an animal’s needs.  This is sometimes a difficult process as we often will have multiple applications for just one animal!

Thank you for choosing to rescue an animal in need and thank you for choosing the Humane Society of North Iowa!


Who We Are

The Humane Society of North Iowa was founded in 1959 by Alice Anne Blackmore and was located on her farm in Mason City, IA.  Alice Anne cared for hundreds of animals on this farm and created the beginning foundations of an animal rescue organization in North Iowa.

In 1986, David and Phyllis Murphy purchased a retiring Veterinarian’s office on the north end of Mason City and gifted the building to the Humane Society of North Iowa.  Every square inch of this donated space was utilized to the fullest over the next two decades.  Eventually, the demands of the organization had outgrown the size of the building and more space was needed.

In 2006, the MacNider family donated 6.5 acres of land to the Humane Society of North Iowa on which to construct a new facility.  Blueprints were drawn up and plans for a Capital Campaign were made.  In the summer of 2008, the “Making Miracles Happen” Capital Campaign was launched with a goal of $1 million dollars.

The Humane Society of North successfully concluded it’s campaign in just two short months having met it’s $1 million dollar goal.  Ground was broken and a 6400 square foot facility was constructed  and opened to the public in the summer of 2009.  This new facility has space for more than 100 displaced animals and includes medical, grooming and quarantine areas.

The Humane Society of North Iowa is considered one of Iowa’s largest “no-kill” shelters, meaning that animals are not euthanized based on the length of time they’ve been in the shelter or due to a lack of space.

The Humane Society of North Iowa is proud of the work we’ve done for the animals, people and community in which we serve.  In the past 25 years, the Humane Society of North Iowa has found loving homes for over 8000 abandoned, displaced, and neglected animals!!
