TNR – Trap Neuter Return (Cats)
Helping Community Cats Live Healthier Lives
The NSPCA’s Trap Neuter Return (TNR) programme is a subsidised neutering service for unowned and community cats. TNR is a humane and effective way to manage cat populations while improving the welfare of cats living outdoors.
By preventing unwanted litters, TNR helps reduce the number of vulnerable kittens born each year and allows community cats to live healthier lives within the environments they know.
Why is TNR Important?
Cats can begin breeding from as young as five months old and may have multiple litters each year.
Just one unneutered male and female cat can produce:
Neutering is one of the most effective ways to prevent overpopulation and reduce the number of cats facing hunger, illness and homelessness.

TNR FAQs
How can I tell if the cat belongs to someone?
Community cats are often wary of people and prefer to keep their distance, even if they regularly receive food from local residents.
If you’re unsure whether a cat has an owner:
- Take a photograph and ask locally through community groups and social media.
- Check with neighbours and local residents’ associations.
- Contact nearby veterinary clinics or rescue organisations for advice.
If the cat is comfortable being handled or actively seeks human attention, there is a good chance they may have a home nearby. Cats can roam surprisingly large distances, so it’s always worth checking before arranging TNR.
How should I prepare for trapping?
The most important step is to stop feeding the cat for 24 hours before trapping.
While this can feel difficult, a hungry cat is much more likely to enter the trap. Continuing to provide food beforehand is one of the most common reasons trapping is unsuccessful.
Fresh water should still be available during this period.
When do you trap cats?
Cats are most active at dawn and dusk, which is why traps are typically set in the evening as daylight begins to fade.
The quieter environment and increased cat activity during these hours help improve the chances of a successful and stress-free trapping process.
Is trapping humane?
Yes. The safety and welfare of the cat is always our top priority.
We use only humane traps specifically designed for TNR programmes. Cats are not harmed during the trapping process, and trapping will only take place when it is safe to do so. We do not trap during unsuitable weather conditions or if there is any risk to the cat’s wellbeing.
How do I know if a cat has already been neutered?
Community cats that have been through a Trap Neuter Return (TNR) programme can usually be identified by an ear tip.
An ear tip is the safe and humane removal of a small portion of the tip of one ear while the cat is under anaesthetic during their neutering procedure. It is an internationally recognised sign that a community cat has already been neutered.
Ear tipping is only carried out on unowned community, feral, barn or farm cats and is not performed on pet cats.
