Hi Jennifer
This is what my vets and I have developed through testing since I started the TNR programme 5 years ago. Generally it is a same day evening return, or next morning.
The surgery team has worked out a specific protocol for TNRs, using extra internal stitches and more glue, to enable this faster return to field and a very secure surgical wound.
All our surgeries are done early in the day, so the cats are finished by 11.30, with the aim to release later in the day for as many cases as possible. If the surgeries are in the afternoon for any reason, they'd be released the next morning.
Males are given the lightest sedation possible so they are basically fully alert by 12.30. Uncomplicated surgery - they are held in their traps until about 17.30 (5.30 pm) and released.
Males with complications (cryptorchidism, teeth needing removal or badly infected wounds) - 5-7 day hold in cages, not the trap, for antibiotic therapy and fuller recovery.
Females with no complications - if they are fully alert and happy, they are released about the same time as the boys, but if they seem a little groggy, they are considered for release about 21.00 (9pm) and if not ready, have an overnight in the trap and go back early morning.
Females with spay/abort or internal infection, retained foetuses, teeth removal etc, I hold in cages for 5-10 days. Aim is to return at 6 days in most cases. If the cat is very distressed and not adjusting to the cage, she would be released sooner, after consultation with the vet. Our cages can be put in the car, so they're released straight from cage to colony.

Subject: How long to hold TNR cats for recovery after surgeries
Hello everyone,
We are developing Standard Operating Procedures for a collaboration of various volunteers and groups to work together on a TNR program doing mass-trapping projects. One of our most argued over topics among the various participants is how long should we hold TNR cats for recovery after their surgeries.
My standard practice has been to return males and females who weren't pregnant or in heat on the day after their surgeries. I would hold females who were pregnant or in heat for about 48-72 hours after surgery depending on how stressed they seemed.
Other group participants want to hold for less time, others want to hold for more time, and it's been a source of friction. So I'm looking for any general guidance from experts (especially medical experts) on this topic.
