How it works

Why two tags: one each, or one on and one ready

Illustrated man kneeling between two cats, one wearing the Avocado Cat Smart ID Tag and one the Donut, holding up his phone with two pets listed in the Ask A Vet app

One tag each, one profile each

Each tag opens its own profile in the Ask A Vet app: her name, your numbers, the medical line that matters for that cat.

  • An alert that says which catA finder scans the QR with a phone camera or taps the NFC chip, sees what you chose to share, and you get an alert that says which cat, with the scan's location where the phone shares it.
  • Two cats, two tagsTwo cats, two tags, no mix-up.

The spare, for the day the collar comes off

A cat's collar must open under her weight, so sooner or later it does, and the tag goes with it.

  • On the new collar that afternoonThe second tag is the one that goes on the new collar that afternoon, activated to the same profile or its own, so she is not out for a week with nothing on her.
  • On the harness or the carrierA spare also lives on the harness for walks, or on the carrier.

Nothing to charge, nothing to renew, less than two apart

The QR is printed and the NFC chip is passive, so neither tag has a battery, and the profiles are free for life, so there is no subscription to forget.

  • Small or Medium, any two designsBoth tags come in one size, Small for a cat whatever her size or Medium for a wide collar, in any two of the fourteen designs.

  • Both tags come in the size you pick, so the set is for two cats who take the same size, or one cat and her spare. Small is the tag for a cat whatever her size; Medium is larger, easier to scan at arm's length, for wide collars or big cats who do not notice it. A big cat and a kitten who need one of each buy two single tags today.

  • Any two designs, the same or different, and the Slide-On counts as one: it threads flat onto the strap for the cat who chews whatever dangles. In Medium, only some pairs are on the listing today; a greyed swatch means the pair cannot be ordered yet, not that it is sold out.

  • Breakaway collars only, for both cats: a collar that opens under her weight if it catches, fitted with two fingers flat under it, checked weekly, and every few days on a kitten. The tags are on top of the microchips, not instead of them; keep both registry numbers current too.

How to

How to activate two, fit two, and keep the spare useful

  • Illustrated man on a couch with a cat, phone in hand, the Avocado and Donut Cat Smart ID Tags lying QR side up on the coffee table

    Activate both before either goes on a cat

    Scan each tag yourself; each opens the setup page for the Ask A Vet app. One profile per cat, or both tags on one cat's profile if the second is her spare. Ten minutes on the couch.

  • Illustrated man kneeling beside a cat wearing the Avocado Cat Smart ID Tag, pointing at the owner and pet details on his phone's public profile screen

    Put on each what a finder needs

    Two phone numbers, one of them not yours. Her name. The medical line that matters for that cat: on medication, indoor only, do not feed. Not your address.

  • Illustrated man holding a purple collar open in one hand and steadying a cat's collar with the other, the Avocado Cat Smart ID Tag hanging from its D-ring

    Onto breakaway collars

    Clip ring through the D-ring; the Slide-On threads onto the strap. Two fingers flat under each collar, and each collar opens if you pull it hard.

  • Illustrated man and woman kneeling at a low table with two cats, her phone showing a cat's public profile and his the scan alert, the Avocado and Donut Cat Smart ID Tags on the table

    Test both with someone else's phone

    Have a friend scan each code and tap each tag. Check each profile shows the right cat, and check the alert names the right tag on yours.

  • Illustrated man crouching to put the Donut Cat Smart ID Tag into a drawer, a cat wearing the Avocado tag QR side out watching

    Keep the spare where you can find it

    The drawer by the door, or on the harness. The day a collar comes off, the spare goes on the new one before she goes out again.

Vet noteDr Duncan Houston, emergency veterinarian

A cat collar must be a breakaway collar, one that opens under her weight if it catches on a branch or a fence, and these tags go on nothing else; a fixed collar with a dangling tag is a strangulation risk, and the emergency room sees the result. Fit each with two fingers flat between collar and neck, check them weekly, and check a kitten's every few days, because she grows out of it in a month. The tags are on top of the microchips, not instead of them: the chip is what a vet or a shelter reads when a cat arrives without a collar, so keep both registry numbers current too. A cat who chews at the charm gets the Slide-On, and a charm with a chewed edge comes off before a piece of it is swallowed. Two cats who share a house share parasites and infections, so when one comes home after days away, both get looked at. If they go outside, a bell on the collar is a separate decision, and the birds would like you to make it. A collar that has caught, or a swallowed piece of charm, is a same-day vet visit.

Why two

Two cats need two tags. One cat needs a spare.

Breakaway collars are meant to come off, and they do, in a hedge or on a fence. When one goes, the tag goes with it, and the cat who most needs ID is the one who has just lost her collar somewhere she should not have been. A spare in the drawer goes on the new collar the same day. For two cats it is simpler: one each, one profile each, so a finder reaches you about the right cat. Either way this is the one set on the store priced below its parts, on purpose. Gary wears the Sardines; the spare waits.

    • Two battery free tags ensure both cats wear identification simultaneously without maintenance. The no subscription model appreciably reduces long term ownership costs.

      DenyJune 2026

    • I bought the bundle and split it as gifts for two cat-owner friends at different life stages — one chose the dumpling, one chose the sardines. Both were received with genuine delight and both friends have since messaged to say the tags have worked perfectly. A practical and charming gift solution.

    Shipping and delivery detailsHow returns work
    Do both tags have to be the same size?

    Yes, on this listing: the size you pick is the size of both. That suits two cats who take the same size, which is most pairs, and it suits one cat with a spare. A big cat on a wide collar and a kitten are two single tags today, and the page for the single tag has the sizes. Small is the tag for a cat whatever her size; Medium is the larger one for wide collars.

    Can I put both tags on one cat?

    Yes, and it is one of the two reasons the set exists. Activate the second tag to the same profile, or give it its own, and keep it on the harness, on the carrier, or in the drawer by the door. Breakaway collars come off, and the spare goes on the new collar the same day, so she is never out for a week with nothing on her.

    Do I need a subscription?

    No, for either tag, ever. Each profile is free for life; you change your number, your address or a medical note in the Ask A Vet app in seconds and the tag on the collar is up to date the same moment. The app's Premium plan is a separate thing for the GPS trackers and the vet chat, and nothing about these tags needs it.

    Why is a swatch greyed out in Medium?

    Because that pair is not on the listing yet, not because it is sold out. Shopify allows 250 variants on one product and two sizes by fourteen designs by fourteen designs is 392, so the listing stopped part way through Medium; it is being fixed. Every Small pair is there. If you want a Medium pair that is greyed out today, email hello@purrz.com and we will set it up by hand.

    What does a finder see, and what do I get?

    The finder points a phone camera at the QR code on the back, or taps the tag with a phone that has NFC, and that tag's profile opens in the browser: no app to download. They see what you chose to show, your numbers, her name, the medical line, and a button to tell you she is found. You get a notification naming which tag was scanned, with the scan's location where the finder's phone shares it.

    Are they right for a kitten, and are they safe on a collar?

    A kitten wears the Small on a breakaway collar checked every few days, because she grows out of a collar in a month. A cat who chews at whatever dangles takes the Slide-On as one of her two, which threads flat onto the strap. Every collar these go on must open under her weight if it catches: a fixed collar with a dangling tag is a strangulation risk, and the emergency room sees the result.

    What if one arrives damaged or the wrong design?

    Email hello@purrz.com within 7 days of delivery with a photo and your order number; faulty, damaged or incorrect items are covered and we pay the return shipping when the error is ours. A tag that will not scan out of the box is a fault, not a setup problem: send the photo, and activate the other one in the meantime so at least one cat is covered.

    Two profiles live in the Ask A Vet app. The tags are the doors to them.

    PURRZ™ is the cat product arm of Ask A Vet, Dr Duncan Houston's animal health platform. Each tag's profile sits beside her weight, vaccinations, symptoms and reminders in the same free app, and a certified vet is there to chat to when something is not right.
