Trap-Neuter-Return (TNR) is a nationwide effort to control the outdoor/community cat population by spaying or neutering them, allowing them to stay in their home environment without adding to the population. Yellowstone Valley Animal Shelter recognizes the need for these services and seeks to provide them at an affordable cost. This program is intended for those caring for unowned community cats within Yellowstone County but outside of Billings city limits. Caretakers enrolled in this program are required to sign up their colonies through Catstats to allow for colony tracking and access to YVAS resources.

Frequently Asked Questions:
Why does our TNR Program only operate within Yellowstone County but outside of Billings city limits?
Due to medical staffing, time, and resources our capacity only allows us to provide services to those within our own county.
YVAS is legally limited in our ability to assist with outdoor cats within city limits due to current ordinances that are in place. See Ordinance 05-5351 Sec. 4-406 of Billings city ordinances.
What cats qualify for this program?
TNR is intended for unowned outdoor cats that are not spayed or neutered and are located outside of Billings city limits. These cats may be feral meaning they avoid human interaction. TNR is NOT intended for regular housepets. People seeking spay/neuter services for their pets can sign up for one of our regular spay/neuter appointments.
What services are provided for TNR cats?
TNR is $25 per cat and includes the following:
- Spay/Neuter

Vasectomy vs. Neuter
Additionally: Male vasectomies are optional at $45 per cat and covers all of the above services the additional vet time and a FELV/FIV test.
Vasectomy:
A vasectomy is recommended for those that live in more remote areas and would like to keep their cat population stable. This surgery ensures that they are no longer able to reproduce but allows them to keep producing testosterone. This means that they will still continue to spray, chase other males away, fight and attempt to mate. Males that go through this surgery must be well established and preferably the dominant male in the colony as well as pass a FIV/FELV test to ensure they are able to recover from the more invasive surgery and will not be sexually contagious to other cats.
Neuter:
A neuter is recommended for those wanting to reduce the nuisance of having cats or that live in closer vicinity to others that might find the cats a nuisance. This surgery completely removes the testicles and therefore testosterone and mitigates the urges to spray, fight and yowl as well as any mating behavior.
Can YVAS rehome any of these cats for me?
No, the purpose of TNR is to RETURN the cats to their original location. This is done to ensure that they continue to live a quality life in a place they are familiar with and means that new cats will not replace those that were removed. While YVAS does have a barn cat program, it can only accommodate eight cats at a time from inside Billings city limits and these slots are reserved for community cats do not have a safe environment they can return to.
Can TNR be done in the winter?
While TNR in winter can be trickier, it absolutely can be done! Community cats are accustomed to living outdoors and the temperature fluctuations that come with it, their body temperature is naturally around 101-102.5 degrees and combined with their thick winter coats keeps them nice and warm in the chilly Montana weather. The biggest things to be aware of when it comes to winter TNR is that the weather might not agree with your trapping plans. Extreme weather conditions might be the cause of a last minute rescheduling to ensure the trapping is successful and the cats are able to go back without having to deal with extreme temperatures. Cats trapped in the winter should be placed in a sheltered area out of wind or weather off the cold ground, preferably with the traps covered to provide an additional wind block. After surgery they should be bright eyed and fully awake before releasing and have access to food, water and shelter to allow them to fully recover after being released. Providing a mix of wet and dry food can help with this as the wet food will help hydrate when water sources may be frozen and the dry will provide additional calories to help keep them warm.
