Return To Good.

We are proud to announce our giving back program, Return To Good! We love what we do and want to give back to support the mission of saving and improving the lives of our pet population. We consider pets to be members of our family but many animals lack a loving home and are victims of abuse and neglect. Our hearts go out to those in need and are thankful for the pet shelters leading the charge to save them. These shelters operate through donations and volunteers, so they often need as much help as we can all give. 

Modko stands behind the quality of our products and accepts returns for our litter boxes that fit the return criteria. Our customers will receive the respective refund while we donate these boxes to our partner shelters so they can put them to immediate use. With Return To Good, Modko is committed to supporting animals in need and we hope each and every one has the very best chance at a happy and healthy life.

The three shelters below have eagerly collaborated with us and we are excited to be partnering with them to introduce this program. These amazing non-profit, no-kill shelters provide outstanding services to our animals and communities. We hope Return To Good can help these amazing organizations and their selfless staff in some small way to continue doing great things!


Social Tees Animal Rescue (S.T.A.R.) is a non-profit, strictly no-kill 501c3 organization that takes abandoned animals from the kill shelters and provides them with a safe haven and veterinary care until they are placed in a proper home.  

We rescue, rehabilitate and place over 3000 dogs, cats, birds and reptiles per year. All dogs and cats for adoption are spayed/neutered, tested, vaccinated, de-wormed, de-flead, de-mited, microchipped and more. We also run a special program for underdogs and undercats. We house over 20 feral cats and take on as many amputees, blind, and injured animals as possible before they are euthanized.


The Lange Foundation was founded in 1993 by Gillian Lange, recipient of the City of Los Angeles St. Francis of Assisi Award in recognition of her work on behalf of abandoned and neglected animals since 1974. To date, she has helped rescue and place over 20,000 cats and dogs that would have otherwise been destroyed in shelters.

Lange Foundation is dedicated to saving impounded companion animals, and preparing them for a journey to a new safe, loving world. We have also initiated an ongoing sterilization program, to dramatically reduce the number of unwanted pets born in Los Angeles County.


Tree House Humane Society is the largest cageless, no-kill shelter for injured, sick and abandoned cats in the Chicagoland area. Since its founding Tree House has found homes for more than 16,000 "residents." In addition to our focus on the rehabilitation and adoption of stray cats, we offer many other valuable programs and services, including our Free Spay/Neuter Program, Pet Loss Grief Support Group, Humane Investigations Team, Youth Volunteer Program, Animal-Assisted Therapy, Behavior Hotline, Pet Food Pantry, and Education Outreach Program.

Tree House is a 501(c)(3) non-profit charity, and all donations are fully tax-deductible. We do not accept any federal or state funding. Almost all of our support comes from concerned and involved individuals like you.
