There are both GPS trackers and radio-tracking devices available to help you find your cat if they ever go missing.  This article explains how both types of devices work and their pros and cons for use with cats, especially since many of them are designed for dogs.  All of the devices described here must be attached to either a collar or harness.  Several research studies have found that the risk of cats getting injured by a collar is highly exaggerated, and your cat is at a much higher risk of becoming lost and never found.  Contrary to the belief of some lost pet owners, microchips do not have any tracking abilities.  In order for your cat to be found with a microchip, they must be caught and brought into a vet or animal shelter where they can be scanned (and the microchip must be registered and have up-to-date contact information).

GPS trackers rely on satellite signals and can remotely tell you where you cat is located as long as it can pick up a signal.  The location can often be transmitted to your computer or cell phone.  One main drawback to GPS trackers is that they may not be able to transmit a signal if your cat is in a building or underground or sometimes even if the sky is heavily overcast.  However, some GPS trackers also use cellular signals and this can increase reliability depending on coverage.  These are called A-GPS or Assisted GPS.  There is usually some error in the transmitted location and you will probably have to physically search an area to find out exactly where your cat is located.  GPS trackers also require payment of a monthly service fee or prepay program similar to cell phones.

Perhaps the biggest drawback of the GPS is its relatively short battery life.  I use Tagg the Pet Tracker on my dog, and I have to recharge it every 1-2 weeks.  As long as your pet remains within the home area the tracker will remain in power-saving mode and could last up to a month (in theory).  However, when I travel away from home with my dog, the GPS battery dies within 2-3 days.  The Tagg tracker will text or email you an alert when the battery level is low.

There are numerous dog GPS trackers but most are too heavy for a cat.  The recommended maximum weight for a cat to carry is 40 grams or approximately 1.5 ounces.  There are  several GPS trackers designed for cats that are available in the US, but even these are generally only recommended for cats weighing 10 lbs or more.  These include the GPS CatTrack Live (TK201) available from Mr. Lee’s CatTrack and Tagg the Pet Tracker.  PawTrax, which offers a pre-payment plan rather than a monthly fee, may now be available for purchase in the US.  Pawtrack created a new GPS tracker designed specifically for cats, but as of July 2015, these are not yet readily available.

With a radio-tracking device, your cat wears a small transmitter on his/her collar, and you have to walk around with a receiver to try and locate the cat.  The basic principal is that the receiver will beep louder the closer you get to your cat.  Radio-trackers can transmit signals through buildings, so you can still locate your cat if s/he was trapped in a shed or basement.  The main drawback to radio-collars is that they usually have a limited range, generally anywhere from 100 feet to 1 mile depending on the strength of the signal and the terrain you are searching.  The signal will travel much farther in open areas compared to wooded areas or through buildings.   You may need to practice a lot with your radio-tracker to become proficient with using it.

There are currently two radio-tracking collars available in the US: the Loc8tor Pet and the LoCATor.  The Loc8tor Pet costs around $100 (for 2 transmitters and 1 receiver) and has a maximum range of 100-400 feet.  The LoCATor costs $50 per radio-collar and $250 for the receiver and antenna, and it has a maximum signal range of 600 feet (city) to 1 mile (open country).  To operate the LoCATor you are also legally required to obtain an Amateur Radio Operators license from the FCC.

Radio-tracking devices are a good option for finding a lost cat for several reasons:

  • Most lost indoor-only cats do not travel more than 500 feet from where they go missing and nearly all of them are found within 1/4 mile.  (Lost outdoor-access cats may travel a mile or more from home so adding a GPS would be the safest option if you can afford it.)
  • Lost cats have a greater tendency to get lost and trapped within their own homes or outside in sheds, garages, and basements.
  • Cats are excellent hiders and a lost cat will frequently run and hide even from their owners.  A radio-tracker allows you to track down the exact location of your cat while a GPS tracker will just give you a general area.
  • Radio-trackers are much smaller than GPS trackers and can easily be attached to a break-away cat collar.  Also if your cat loses their collar, you should still be able to locate the collar and tracking transmitter.
  • Batteries will often last 4-6 months (at least in the Loc8tor Pet) before requiring replacement.  (However, unlike the Tagg GPS, they will not warn you when the battery level is low.)

I originally wrote this article in 2011 and have updated it over the years (most recently in 2015).  At this point, I still recommend the Loc8tor Pet for indoor-only cats, but for outdoor-access cats, I actually recommend both a GPS collar and radio-tracking device if you want to be extra-safe.  I’ve had several outdoor-access cats go missing while wearing the Loc8tor Pet and it was difficult to locate them.  In both cases, posters had to be used to generate sightings and then the Loc8tor was used to track down the cat at the sighting.  At this point, most of my experience is with the Loc8tor Pet and Tagg the Pet Tracker.  However, I am hoping to purchase and try out the Pawtrack GPS in the near future.

  1. I just wanted to make it clear that I currently only have hands-on experience with the Loc8tor Pet. However, I have also previously worked on several wildlife research projects using radio-telemetry to track wolves, bears, coyotes, and foxes. Not surprisingly, I am a little biased towards radio-tracking. I do have experience using GPS locators and GPS loggers, but not any of the ones designed for finding lost pets. I plan to acquire and test more GPS and radio-tracking devices in the future.

  2. As a wildlife biologist who used radio telemetry for many years for everything from spotted owls, to mountain goats, and Canada lynx….here is one thing to remember. You must turn the signal down until it is barely audible…then as you walk around it will either get louder or disappear. You know you’re heading the right way if it gets louder and louder which is why we turn it down so low in the beginning. It’s easier to detect the sound disappearing entirely or getting slightly louder if it’s kept at a very low volume…that way the only way it will get perceptibly louder is if you are getting closer to the animal. Also, there are a LOT of things that can interfere, buildings made of concrete, canyon walls, hills, etc. The signal can “bounce’ off of canyon walls and confuse the user. We often had to use helicopters/small aircraft which are, of course, not an option for cat owners…but we used them to prevent the “bounce” issue. You want a collar that has the closest possible accuracy, for example…down to 100 feet versus 200 feet. They’re a great tool, but still not infallible.

  3. Well, is it possible then to have BOTH! mount the radio-tracking device onto the GPS collar. If your cat is worth its life, then why not have both. That way you are sure to locate the exact venue and find your cat without much difficulty.

    • Earlier this year, I purchased a Tagg the Pet Tracker for my dog. I also attached a Loc8tor radio-tracker to his collar. This way the GPS gets me to the general area, and then I can find his exact location with the radio-tracker. So I would definitely agree that if your cat is big enough, using both is the best option. BTW: my dog also has a microchip and an ID tag because you can never be too careful.

  4. I think they might have those kinds of collars here: http://www.trainingcollarstore.com

  5. Pawtrack now has a GPS that is designed specifically for cats and built into the collar. I will probably need to update this article after I learn more about these trackers and maybe even try one myself. For more information see: https://www.kickstarter.com/projects/pawtrack/pawtrack-gps-cat-tracking-collar

  8. I have both the Loc8tor and the LoCATor radio trackers. The LoCATor is better in every way, and I no longer use the Loc8tor.

    I have not tried any GPS unit, but the perpetual service fees and constant battery re-charging are real turn-offs.

    More to the point, my LoCATor can find my cat hiding in a specific rainwater sewer grate among other sewer grates that are less than 10 feet away. And 15 feet up a garage wall hiding behind a specific trim piece that makes the cat invisible from ground level.

    Try THAT with a GPS !
    Bottomline: GPS collars are just too imprecise, too big, and too power-hungry to be an effective solution for cats. Fine for dogs, but cats are a whole different “animal”.

  9. I found another GPS collar (for cats only) which looks and works even better than the pawtrack collar which I purchased/received a few month ago. Unfortunately the KADDZ GPS Collar is currently only available in Europe. More about: http://www.kaddz.com/en/.

    Or watch this short introduction video:

    It would be great if the KADDZ collar could be also tested/presented in this article in order to get an better overview of all current available GPS cat collars. Thanks
