Animal welfare with heart and mind: Since 2000, the Susy Utzinger Foundation for Animal Welfare has been working to sustainably reduce or even prevent animal suffering in Switzerland and many other countries.
Through effective means, the Susy Utzinger Foundation for Animal Welfare contributes to sustainably reducing or even preventing animal suffering in Switzerland and many other countries.
All over the world, countless animals lead a miserable existence in overcrowded shelters or struggle for survival in feral colonies. Even today, every day, animals deemed a nuisance are abandoned, deported, or kept improperly due to a lack of knowledge.
The SUST therefore focuses not on the consequences, but on the causes. Its work is based on four interconnected pillars. In addition, it provides immediate assistance to those animals that cannot wait until this reconstruction work takes effect.
Each individual pillar works independently. Together they ensure that fewer animals are in distress and that aid continues on the ground even after the SUST has departed.
Animal shelters are becoming high-quality transitional facilities for homeless animals, where they are kept and cared for in a species-appropriate manner and ultimately placed in good new homes. SUST advises partner animal shelters, supports construction projects, and provides food and supplies.

Curbing animal suffering: Castration is the only way to control the overpopulation of stray animals in a sustainable and humane manner. SUST conducts castration campaigns in Switzerland and abroad and supports local organizations in this endeavor.

Professionals are given the opportunity to optimize their knowledge and improve animal welfare. This includes training for veterinarians, continuing education for animal care staff, internships, and the SUST Academy.

Animal love with heart and mind: SUST provides pet owners and animal lovers with the knowledge to prevent animal suffering before it occurs.
information and educationThese four elements form the important basis for sustainable animal welfare projects.
Those animals that have not yet benefited from the effects of this reconstruction work and were born into a world where they are not wanted need the immediate help of SUST.
As of September 2026. The castration figures are continuously updated and can be viewed on the Castrations page.
The purpose of a foundation is only as valuable as how it is managed. These principles have been in place since its inception.
SUST is not affiliated with any umbrella organization or other body. It decides independently where it provides assistance.
The annual accounts and activity report are audited annually by the Federal Department of Home Affairs as part of its statutory supervisory duties (Art. 84 para. 2 of the Swiss Civil Code).
All animal welfare activities are financed through donations and bequests. The foundation receives no public funding.
The foundation's board of directors works on a voluntary basis and contributes expertise in veterinary medicine, law, and business administration.
SUST has virtually no budget for advertising or marketing. Its infrastructure is geared towards animal welfare work, not the other way around.
A flat structure and fast decision-making processes are crucial in animal welfare: rapid interventions save lives.
Every pillar of this work is supported by the people who fund it. A donation to SUST goes towards projects that will still be effective years from now.
