Fi Mini GPS Pet Tracker Fits on Cats and Small Dogs

Fi Mini brings true GPS tracking to cats and small dogs

Fi, known for its smart dog collars, has launched the Fi Mini: a clip-on GPS tracker designed to be small and light enough for cats and small dogs. It starts shipping September 1 and comes with a subscription option priced at $129 per year.

At 0.56 ounces (16 grams) and sized 42mm by 30mm, the Fi Mini is slightly larger than an AirTag but still compact enough to fit on collars between 3/8 and 1 inch wide. It uses Verizon’s LTE-M cellular network for live location updates and walking history.

Key specs and features

• Weight: 16 grams (0.56 oz)
• Dimensions: 42 mm × 30 mm
• Connectivity: Verizon LTE-M for real-time tracking
• Battery: up to 3 weeks on device; up to 3 months with Fi base
• Durability: IP68 water and dust resistance
• Charging: USB-C and app-based live tracking

Beyond location, the Fi Mini mirrors the company’s smart collar features: activity and sleep tracking today, with AI-powered behavior detection (barking, scratching, eating, drinking, licking) arriving this fall. Apple Watch integration is also on the roadmap.

Why this matters

For pet owners, Fi Mini offers higher location accuracy than Bluetooth trackers and a form factor light enough for most cats. Real-time escape alerts and live tracking reduce the time and stress of locating lost pets.

For the pet-tech market, the launch signals continued interest in tiny, cellular-connected devices and subscription models. It’s also notable in light of recent consolidation: Tractive’s acquisition of Whistle and the shutdown of that tracking platform leave room for new entrants and differentiated offerings.

Considerations for product and operations teams

Decisions about connectivity (LTE-M), battery life trade-offs, subscription pricing, and privacy controls will shape user adoption. Manufacturers and retailers should weigh bundling the device with base stations, promotions for first-year subscriptions, and integrations with vet clinics or local shelters.

Municipal animal services and veterinarians could use compact GPS tags to speed reunifications and monitor recovery after procedures. That opens routes for pilots and public-private partnerships that lower lost-pet time and shelter load.

How organizations can respond

Teams evaluating the Fi Mini should run small pilots to validate battery life in the field, test LTE-M coverage in target geographies, and measure retention tied to behavior alerts. Privacy and data residency will matter for vets and public agencies, so clarify data access and retention policies before wider rollout.

Fi’s Mini is available to purchase now and begins shipping September 1. For pet owners who need a smaller GPS option than a collar, and for businesses looking to expand pet-monitoring offerings, it’s a noteworthy addition to the growing IoT pet-tracking landscape.

QuarkyByte’s approach is to combine device telemetry analysis with market and privacy risk assessments to help partners design pilot programs, model subscription economics, and optimize coverage strategies. Whether you’re a retailer planning bundles or a municipal team exploring tracking pilots, the Fi Mini is worth evaluating.
