General Information

Please be aware that our clinic currently has an active wait list of about 3-6 months before you will be offered spaces.  Once you have requested clinic space, you are automatically put on the list in the order your request was received & you will be contacted regarding trapping once your turn has arrived.  You do not need to resubmit a clinic request form for the same colony if you are on the wait list; however, each colony requires it's own request.  When you are emailed regarding trapping, YOU MUST RESPOND TO THAT EMAIL TO CONFIRM YOU CAN TRAP FOR THAT CLINIC.

Please make sure you are checking your email frequently so you don't miss your chance at clinic .

We highly encourage caretakers with 1 to 3 cats to purchase/apply for vouchers.  This allows us to get the larger colonies into the clinic.

Beginning April 2023:  We will be alternating our clinics between small colonies (19 cats or less) and large colonies (20 cats or more).  In April, we will only offer space to small colonies.  In May, we will only offer space to large colonies.  We will continue to alternate like this until we are only doing large colonies.  This way, if a small colony requests space, we can contact a larger colony caretaker(s) to bring fewer cats to clinic and work the small colony in. We are hoping this new strategy will enable us to get further down our waitlist and getting some of the smaller colonies done sooner.  Please feel free to email April at if you have any questions regarding this new approach.

TNVR Wake Colony Registration


TNVR Wake is a program that allows you to register your colony.  There are many benefits for registering your colony.  One of the main benefits is that colony registration makes it easier to reclaim a colony member if they find themselves at Wake County Animal Center.


All information shared with TNVR Wake is kept in the strictest confidence and is not shared out to third parties without written consent.


You will be asked to enter your email address for colony registration.  As Operation Catnip does not give out that kind of information, we are no longer entering colonies in the TNVR database.


Operation Catnip WILL continue to use basic, non-identifying information (zip code and colony numbers) for our grant applications.  No individual names, addresses, email addresses, phone numbers or identifying information is used for this purpose.


Operation Catnip does not sell or give out personal information to include caretaker names, addresses, email addresses, phone numbers, or colony addresses to anyone for any reason.  We will not even confirm if someone is on our wait list.


If you would like to register your own colony, you may do so at  The website has a wealth of information and we encourage you to take a look.

Operation Catnip highly encourages caretakers to re-vaccinate colony members.  Trapped cats that have an ear tip can be re-vaccinated with a 3 year rabies vaccine and an FVRCP booster.  The cats are NOT examined as part of this service.  Please plan on waiting for your colony member.  While we do not charge a fee, we do request a $5 donation for re-vaccinations.

Please fill out the form to be placed on the roster for an upcoming clinic.
