FAQ
What is PetTag, and how does it work?
Whisker PetTag is a lightweight, smart RFID, pet ID system. RFID, or Radio Frequency Identification, uses radio waves to automatically identify and track objects. The PetTag contains a passive RFID chip with a unique ID. When your pet wears the tag and approaches within 1-8 inches of a compatible Whisker robot, the tag is detected automatically via the robot’s built-in reader. When your PetTag is assigned to a pet, your compatible Whisker robots can identify via RFID which specific pet is using them.
Does PetTag require charging or batteries?
No. PetTag is powered by your Whisker robot, so there's nothing to charge or replace. It works whenever your cat is near the robot, which keeps it low-maintenance and safe for everyday wear. The QR code on the tag is always ready too, so you have peace of mind if your cat ever gets lost.
Which Litter-Robot models are compatible with PetTag?
PetTag is compatible with Litter-Robot 5 Pro models.
Why do I need a PetTag if my Whisker robot has a camera that can identify my cats?
PetTag provides a reliable, unique ID for each cat that works independently of the camera. While cameras use appearance (like color and shape) to identify pets, PetTag uses RFID technology to give every cat a guaranteed, consistent digital ID. This makes detection more accurate in multi-cat homes, in low light, or when cats look similar.
Do I need one PetTag per cat?
Yes. Give each cat their own tag and manage them all in PetTag Manager in the Whisker app.
How do I set up my cat’s profile with PetTag?
Open the Whisker app or download the Whisker app from the App Store or Google Play. Tap “Add Device” in the app, then select “PetTag”. Follow the prompts to onboard your PetTag and assign the tag to a pet profile. Learn more about how to get started with the Whisker PetTag.
Is PetTag water-resistant and durable enough for outdoor use?
Yes. It's IP65 water-resistant, so it's safe for rain, splashes, and everyday messes, and it suits indoor and outdoor cats alike. Wipe it clean; avoid soaking it or using hot water to clean it.
How do I clean the PetTag?
Wipe the PetTag with a soft, damp cloth or cleansing wipe; air-dry before use.
Can the PetTag locate my pet if they get lost?
No. PetTag is not a tracking device. Lost Pet protection can help if your cat ever goes missing: anyone who finds your cat can scan the QR code on the tag and share their contact info with you. If you'd like location tracking for outdoor use, a GPS collar or an AirTag would be needed.
At what age/weight can my cat wear the PetTag?
PetTag is lightweight and safe for cats of all sizes—but because it attaches to a collar, the right age and fit depend on your kitten’s growth. Most cats can begin safely wearing a breakaway collar around 3 months old or 3 lbs, though very young kittens may be too small for a secure fit. If your kitten is under 3 months, we recommend waiting until they grow or using a specialty kitten breakaway collar designed for smaller necks. As kittens grow quickly, always check that the collar fits properly — you should be able to slide two fingers between the collar and your cat’s neck, and adjust as needed. By 6 months of age, most cats are large enough to wear standard cat collars comfortably. For safety, always use a breakaway (quick-release) collar, and inspect regularly for wear or sizing.
Does the PetTag come with a Whisker Cat Collar?
No. The collar is sold separately. You can slide the PetTag onto any cat collar 0.35–0.5 in (9–13 mm) wide, or pick up a Whisker Cat Collar in your choice of colors. All Whisker Cat Collars feature a quick-release buckle that pops open under a gentle pull to keep your cat safe from snags.
What collars are compatible with the PetTag? What collars will it fit?
Any cat collar 0.35–0.5 in (9–13 mm) wide is compatible with PetTag. We recommend breakaway or quick-release collars. Whisker also offers matching quick-release collars in multiple colors.
What is the return policy on the PetTag?
PetTag may be returned within ninety (90) days of receipt for a full refund. You only have to pay return shipping.
RFID disclaimer
RFID detection may be affected by metal tags, microchips, or other nearby RFID devices.
What is Lost Pet protection and how does it work?
Lost Pet protection turns your PetTag into a digital lifeline. If your cat gets out, anyone who finds them can scan the QR code on the tag, with no app or login required. If you've chosen to share your pet's information, they'll see it along with a simple form to send you their contact details, and you'll get an email so you can connect. You never share your own contact info; the finder provides theirs, and you decide how and when to reach out. To make sure your cat's information can be shared, review your Lost Pet preferences in your Whisker account.
Can I turn Lost Pet protection on or off?
Lost Pet protection is part of every PetTag and can't be turned off, but you decide whether your pet's information is shared with a finder. You can update your Lost Pet preferences any time in your Whisker account.
Will finders need the Whisker app?
No. Anyone with a smartphone can scan the QR code—no app or login required.
Will my personal information be safe?
Yes. As the pet owner, you don’t share your personal contact information. Instead, the finder provides their details, and you decide how and when to reach out.
Will it track my pet’s location?
No. Lost Pet protection isn’t a GPS tracker—it’s a simple, app-free way to connect you with whoever finds your pet.
