For Community Cat Colonies: Trap-Neuter-Return-Monitor

Why TNR-M?

"TNR, which stands for trap-neuter-return, is a nonlethal strategy for reducing the number of community cats and improving the quality of life for cats, wildlife and people." The Humane Society of the United States

Given the current situation in the United States, Trap-Neuter(Spay)-Return-Monitor (TRN-M) provides the most humane, effective way to regain control of our community cat populations. To be clear, this is not intended to be a solution: the goal is to decrease the negative impacts of an existing problem (overpopulation) so we can provide a  more humane way of life for cats--stopping a continuous cycle where community cats' lives include unnecessary fear, pain, diseases, suffering, and deaths every year--especially for kittens.


We must look to the future: we cannot back up to change the actions and choices of the past that lead to today's crisis. Rather we must focus on a future and an action plan that will improve quality of life as we gradually regain control of a very serious problem (the unsustainable # of cats in our communities).


Does TNR-M Work?

There is no easy solution: the only way a TNR-M plan truly works is if community members (80%+ of any given area) make the decision and an ongoing commitment to join together to create a future that includes colony cats who have the quality of life they deserve without unnecessary fear, sickness, hunger, disease, and death.

TNR-M Benefits

  • Saves lives--especially kittens

  • Provides improved quality of life for community cat colonies

  • Ensures a safer life, with the elimination of intact male cats stalking and killing kittens

  • Provides a healthier, happier life with less diseases and genetic deficiencies

  • Reduces instances of several negative behaviors (e.g., spraying, howling, fighting)

  • Reduces the number of cats brought to animal shelters because they have nowhere else to live

  • Provides a cost cost-effective, humane way to decrease the negative impacts of uncontrolled cat populations

Help Make our 2024 Spay-Neuter Initiative a Big Success!

Step One

Identify veterinary clinics and veterinarians interested in hosting a feline high-volume spay-neuter clinic

If you have a practice or know of a veterinarian who would like to discuss and help define the partnership model, please contact us. This is a crucial first step: we cannot provide neighborhood clinics without partner veterinary clinics.

Step Two

Identify community cat colonies who need our help

This step is easy--we already have so many community cat colony caretakers who have reached out to us. They really need all of us to join together to help them provide an increased quality of life for the cats they care for every day!

Step Three

Keep $$ coming into the spay-neuter fund

As a part of our key initiative for 2024, HSNEI started a fund at the end of 2023. Thank you all for responding: the fund is growing!!

Step Four

The 2024 goal is to hold 6-8 feline high-volume spay-neuter clinics by the End of Year

For those of you who have not heard about our high-volume clinics: we started holding high-volume spay-neuter clinics in 2023 with our first clinic partner, Northeast Iowa Community College. We are ready for more partners so we can expand into all 5 counties within our service area (Allamakee, Clayton, Fayette, Howard, and Winneshiek). We plan to increase the number of clinics held each year until we reach 24 clinics each year.
