TNR Support Program

TNR, or trap-neuter-return, is the only humane solution to reducing the outdoor cat population over time. Through our TNR program, cats in the community are ear-tipped, microchipped, vaccinated and spayed/neutered to prevent unwanted litters of kittens from being born outdoors. Feral cats who are not socialized to humans are then released back to their outdoor homes in managed colonies, and adoptable cats and kittens will be considered for placement at Heartland Animal Shelter.

If you have free-roaming cats in your neighborhood, send us an email at to discuss our TNR program and services. While we are providing guidance to all those who contact us about outdoor cats and kittens, we have an expended support program for Northbrook residents so be sure to email us if you need assistance or would like to learn more about how you can help our TNR efforts!

If you find kittens outside, please leave them outside and contact us for guidance. In most cases, newborn kittens have not been abandoned! Their mother will leave for several hours at a time so please do not disrupt these kittens unless they are in immediate danger. Kittens who are still nursing have a very low chance of survival if brought to a shelter, even with the best care! To help us evaluate the situation, please consider including a photograph of the kitten(s) with your email message.



When you adopt from a no-kill shelter, you save two lives. The animal you adopt and the one that replaces him.
