Microchip vs Tracking Tags for Cats: What's the Difference?

If you've ever had a cat go missing (even for a few hours), you know the feeling. That sick, helpless moment where you have no idea where they are or which direction to start looking.

Most cat owners assume their microchip has them covered. It doesn't. And understanding why is the difference between finding your cat quickly and waiting by the door hoping they come home.

Here's exactly how microchips and Tracking Tags work, what each one can and can't do, and why the smartest cat owners worldwide are now using both.

What a Microchip Actually Does

A microchip is a tiny RFID chip (about the size of a grain of rice) implanted under your cat's skin, usually between the shoulder blades. It stores a unique ID number linked to your contact details in a national registry.

Here's the critical part: a microchip is completely passive. It has no battery. It emits no signal. It cannot tell you where your cat is.

The only way a microchip helps reunite you with your cat is if:

Someone finds your cat
They take your cat to a vet or shelter
The vet or shelter has a scanner
They actually scan your cat
Your contact details in the registry are up to date

Every one of those steps has to happen in sequence. If your cat is in a neighbour's yard two streets over, or stuck under a house, or has been taken in by someone who thinks they're a stray, a microchip does nothing. You have no way of knowing.

Microchipping is still mandatory for cats in most Australian states, and for good reason. It's the most reliable permanent identification if your cat ends up at a shelter. But it is an identification tool, not a tracking tool. That distinction matters enormously.

What a Tracking Tag Does

A Tracking Tag is a small Bluetooth tracker you attach to your cat's collar. It connects to a crowdsourced network of hundreds of millions of nearby smart devices.

When your Tracking Tag comes within Bluetooth range of a compatible device, that device anonymously and silently relays your Tracking Tag's location to your phone. You open the app and see roughly where your cat is on a map.

In suburban areas, where compatible devices are everywhere, this works remarkably well. Most cats that go missing don't travel far. If your cat is in a nearby yard, hiding under a neighbour's deck, or exploring a few streets over, there's a very good chance a nearby device will pick up the signal and update their location within minutes.

What a Tracking Tag can't do:

Provide real-time continuous GPS tracking (it updates when it pings a nearby device, not constantly)
Work reliably in rural or remote areas with fewer compatible devices nearby
Replace your microchip as permanent identification if your cat ends up at a shelter without their collar

Microchip vs Tracking Tag: Side by Side

Why You Actually Need Both

They solve completely different problems.

Your microchip is your safety net if your cat loses their collar, ends up at a shelter, or is found by someone who does the right thing and takes them to a vet. It's slow, passive, and depends on human action, but it's permanent and foolproof as identification.

Your Tracking Tag is what lets you actively search. The moment your cat goes missing, you open your phone and see the last known location. You know which street to walk down, which yard to check, which direction to call their name. You go from helpless to searching with purpose in seconds.

The two tools are not in competition. They work together. A microchipped cat with no Tracking Tag collar depends entirely on someone else finding them. A cat with a Tracking Tag collar lets you find them yourself.

How to Put a Tracking Tag on a Cat Collar (Safely)

Not every collar works, and how you attach the tag matters for your cat's safety.

What to look for:

• Breakaway buckle: essential for cats. If your cat gets their collar caught on a branch or fence, a breakaway buckle releases under pressure. A collar that doesn't break away can strangle a cat. Never put a non-breakaway collar on a cat that goes outside.
• Built-in tag slot: the cleanest solution. Collars designed with a dedicated holder keep the Tracking Tag flush against the collar, preventing it from swinging, snagging, or being chewed off. Much more secure than aftermarket clip-on holders.
• Lightweight: the Tracking Tag itself weighs 11 grams. Your cat's collar should weigh no more than 10% of their body weight total. For most adult cats, a collar under 30 grams total is fine.
• Waterproof: cats don't avoid rain, long grass, or garden beds. Your collar should be able to handle moisture without degrading.
• Adjustable fit: a collar that's too loose can get caught on things; too tight is uncomfortable. Look for collars with fine-adjustment capability, not just fixed holes.

The WagWells Tracking Tag Collar is built specifically with all of these in mind — breakaway safety buckle, a built-in tracker slot that holds the Tracking Tag flush, waterproof nylon webbing, and a fully adjustable fit. It's the simplest way to set up tracking without bodging together a solution that might fall apart — and now it comes bundled with our own Tracking Tag, so there's nothing extra to buy.

Setting Up Your Cat's Tracking Tag

Once you have the collar sorted:

Remove the pull-tab from your new Tracking Tag to activate it
Pair it with your phone via the companion app
Name it (your cat's name works perfectly)
Attach it to the collar slot
Confirm the location appears in the app

Battery life is approximately 12 months on a standard CR2032 coin battery. The app will notify you when it's running low.

What Happens When Your Cat Goes Missing

This is the moment everything matters.

With microchip only: You call local vets and shelters, post on community Facebook groups, walk the streets calling their name, and wait. If someone finds them and does the right thing, you might get a call. This process can take days.

With Tracking Tag collar: You open the app, see the last known location, and head there. If the tag has pinged recently, you're searching a specific area rather than the entire suburb. Most cats are found within hours.

This doesn't mean a Tracking Tag is perfect — if your cat is somewhere completely isolated with no compatible devices nearby, the location won't update. But in Australian suburbs, that scenario is rare. The network is dense enough that most cats will ping within 15–30 minutes of moving.

The Bottom Line

A microchip keeps your cat identifiable for life. A Tracking Tag collar lets you find them when they go missing. You need both.

If you haven't already set up a Tracking Tag on your cat's collar, it's one of the simplest and most effective things you can do for their safety. The collar takes 30 seconds to put on. The setup takes two minutes. And the next time they slip outside, you'll know exactly where to look.
