Quick Answer: The Weenect XS is the tracker to buy when nothing else is small enough. At 27 grams and 60.5 x 24.5 x 15 mm, Weenect markets it as the smallest cellular GPS tracker on the market (per Weenect), which makes it the standout choice for cats and toy-breed dogs that can’t comfortably carry a Fi collar or a Halo unit. It tracks live over an unlimited-range multi-network eSIM (5G/4G/2G across 170+ countries), refreshes as fast as once per second in Superlive mode, and is IP68 waterproof to 1.5 m. The catches are a short ~2-day continuous battery and a required subscription (about $5.50–$13/month). Hardware is roughly $35. For a small pet that needs true live tracking, it’s the best fit; for a medium or large dog, a Tractive or Fi is the more practical everyday tracker.
Most GPS trackers are built around a medium or large dog. Strap one to a cat or a 6-pound Chihuahua and the device is the size of the animal’s neck. That’s the problem Weenect set out to solve: the French brand’s Weenect XS is deliberately engineered to be the smallest true cellular tracker you can buy, and it’s why the XS keeps coming up whenever someone asks how to put live GPS on a cat. This review covers what the Weenect XS actually does well, where it falls short, how the dog and cat versions differ, and how it stacks up against the trackers we rank in our best GPS dog tracker roundup.
Weenect by the numbers
- 27 grams / 60.5 x 24.5 x 15 mm: the weight and size of the Weenect XS, which Weenect markets as the smallest GPS pet tracker on the market — roughly half the weight of a Fi Series 3 module, and the reason it’s the default live tracker for cats and toy breeds.
- Unlimited range over 5G/4G/2G: the XS ships with a multi-network eSIM that works in more than 170 countries (per Weenect), so there’s no distance limit — if your pet reaches cell coverage, you can see them.
- ~2 days continuous / up to 7 days: the 500 mAh battery lasts about two days of continuous tracking, stretching to a claimed seven days when you use Wi-Fi power-saving safe zones (per Weenect); a full charge takes about 2 hours.
- IP68 to 1.5 m for 60 min: the XS is fully waterproof (per Weenect), on par with the rain-and-puddle resilience of a Tractive or Fi.
- ~$35 hardware + from ~$5.50/month: the device itself is cheap; the true cost is the subscription, which runs from about $5.50/month on a 3-year plan up to $13/month month-to-month (per Weenect).

Weenect XS (Dog) — Smallest Live Tracker for Small Breeds
Weenect XS GPS Dog Tracker
- Just 27 g and 60.5 x 24.5 x 15 mm — the smallest true GPS tracker on the market (per Weenect), light enough for a toy breed's collar.
- Unlimited live range over a multi-network 5G/4G/2G eSIM that works in 170+ countries — no distance limit.
- Superlive mode refreshes location every 1 second during an active chase, the fastest refresh in its class.
- IP68 waterproof to 1.5 m for 60 minutes, plus geofenced safe zones with push alerts.
- Lifetime hardware guarantee on the XS (per Weenect) — Weenect replaces the device if it fails.
- Trade-off: ~2-day continuous battery (charge every couple of days) and a required subscription with no offline mode.
Range and accuracy: unlimited, cellular, worldwide
Weenect’s core strength is the same as Tractive’s — it streams over the cellular network rather than Bluetooth or radio, so there is no distance limit. What sets it apart is the multi-network eSIM: instead of a single carrier’s SIM, the XS hops between 5G, 4G (NB-IoT/LTE-M) and 2G networks across 170+ countries, which helps it hold a signal in patchy rural coverage and makes it genuinely useful for travel. Accuracy in open areas is the usual cellular-GPS ballpark of around 10–30 feet, softening under heavy tree cover or indoors. The standout feature is Superlive, a mode that refreshes position every second — when a cat bolts or a small dog slips a fence, that near-real-time trail is the difference between finding them in minutes and losing the track. It’s the same job Tractive’s LIVE mode does, just tuned a notch faster.
Battery life: the main compromise
The price of that tiny 27-gram shell is a small 500 mAh battery. Weenect rates it at up to ~2 days of continuous tracking, or a claimed 7 days if you lean on Wi-Fi “safe zones” that let the tracker sleep at home. Independent reviewers (Notebookcheck, among others) land in the same range — roughly two days with 5-minute live updates, three to four days if you slow polling to every 30 minutes. Recharge takes about 2 hours. This is the XS’s clear weakness: it needs charging every couple of days, far more often than a Fi Series 3 (up to 3 months) or even a Tractive DOG 6 (~2 weeks). For a cat that comes home nightly, topping it up is easy; for a dog on long unsupervised days, plan around it.
The real cost: cheap device, ongoing subscription
Weenect’s pricing mirrors the whole category — cheap hardware, mandatory subscription. The XS device is around $35, but it does nothing without a plan. Weenect charges roughly $13/month month-to-month, dropping to about $8.33/month on a 1-year plan and around $5.50/month if you prepay three years (per Weenect). Over two years the subscription costs more than the device, so budget it as the true price. One genuine advantage over rivals: a single Weenect app account supports unlimited trackers, so multi-pet households pay per-device subscription but manage everything in one place — handy if you’re also eyeing our best GPS tracker for multiple dogs picks.
Weenect Cat XS — Live Tracking Built for Cats
Weenect Cat XS GPS Tracker
- Same 27 g body as the dog XS, bundled with a lightweight breakaway-friendly cat collar.
- One of the very few true cellular trackers light enough for an average cat to wear all day.
- Unlimited live range and Superlive 1-second mode — see exactly where an outdoor cat roams.
- IP68 waterproof and geofenced alerts for when your cat leaves the yard.
- Trade-off: still a ~2-day battery, and a subscription is required.
Cats are the toughest tracking problem — they’re small, they climb, and most GPS collars are too heavy. The Weenect Cat XS is one of the only true cellular trackers light enough to solve that, which is why it earns a spot in our best GPS cat tracker roundup alongside the cat-tuned Tractive cat tracker. If you’d rather avoid a monthly fee entirely and only need a last-seen location, a Bluetooth tag like an AirTag for cats is the no-subscription alternative — but it can’t track live movement the way the Cat XS can.
Weenect XT — The Rugged, Longer-Battery Option
For bigger or harder-on-gear dogs, Weenect also sells the Weenect XT, a larger and more rugged sibling to the XS with a bigger battery for longer life between charges. It loses the XS’s headline “smallest on the market” advantage but is a better fit for a medium or large dog that doesn’t need the tiny form factor. If you’re in that size bracket, it’s worth comparing against our best GPS tracker for large dogs picks before deciding.
Weenect XT GPS Dog Tracker
- Larger, tougher build than the XS with a bigger battery for longer runtime between charges.
- Same multi-network eSIM, unlimited range, and Superlive 1-second tracking.
- Better suited to medium and large dogs where the XS's tiny size isn't needed.
How Weenect compares to the alternatives
- Weenect vs Tractive: Both are cheap-hardware, subscription cellular trackers. Tractive has a longer ~2-week battery on its DOG 6 and a slightly cheaper long-term subscription, making it the better everyday pick for medium and large dogs. Weenect wins decisively on size (27g, the smallest available) and worldwide multi-network coverage, making it the better pick for cats and toy breeds.
- Weenect vs Fi: The Fi Series 3 is a rugged built-in collar with a battery measured in months, ideal for escape-artist medium and large dogs — but it’s far too big and heavy for a cat or a tiny dog. Weenect is the answer precisely where Fi can’t fit.
- Weenect vs a no-subscription tag: A Bluetooth tag like an AirTag has no monthly fee but only shows a last-seen location via a crowd network, not live movement. If avoiding fees is your priority, read our GPS dog tracker with no subscription guide first — but understand you give up the live tracking that’s Weenect’s whole point.
The bottom line
The Weenect XS wins on the one spec no rival can match: size. At 27 grams it’s the smallest true cellular GPS tracker you can buy, which makes it the best — often the only — live-tracking option for cats and toy-breed dogs. Add unlimited worldwide range, a 1-second Superlive refresh, and IP68 waterproofing, and it’s a genuinely capable little device for around $35 plus a subscription. The compromise is the battery: at roughly two days of continuous use, it needs charging far more often than a Fi or a Tractive. For a small pet that comes home daily, that’s an easy trade for live tracking nothing else this small can deliver. If your pet is a medium or large dog, start with our best GPS dog tracker roundup and the Tractive review instead — and if you specifically need the tiniest device possible, our smallest GPS dog tracker guide puts the Weenect XS in full context.
