Shop Fi Mini for DogsFrequently Asked Questions
What is Fi Mini for cats?
Fi Mini for cats is a compact GPS tracker that attaches to your cat’s existing collar or harness. It uses cellular GPS to track location and adds activity insights, designed with cats in mind.
Does Fi Mini work without my phone?
Yes. Fi Mini uses its own LTE-M cellular connection and GPS, independent of your phone. The Fi app on your phone is how you see location, alerts, and activity.
Does Fi Mini for cats require a subscription?
Yes. Fi Mini requires an active Fi membership for cellular service and app features.
How does Fi Mini attach to a cat collar?
Fi Mini is designed to clip or thread onto a standard cat collar or harness so your cat keeps wearing the collar they’re already used to.
Is Fi Mini safe for cats?
Fi Mini is intended to be paired with a properly fitted cat collar — ideally a breakaway collar designed for cats — so your cat can free themselves if the collar ever snags.
How accurate is Fi Mini for cats?
Fi Mini combines GPS with LTE-M cellular and Wi-Fi awareness. Outdoor accuracy with clear sky is tightest; indoor and densely covered areas can reduce accuracy. It is designed to give you a close enough fix to start a search if your cat is out.
What is the battery life on a cat?
Battery life varies with how often your cat leaves their Wi-Fi base and how much active GPS tracking is needed. Most members get multi-day battery life on a single charge under typical conditions.
Is Fi Mini waterproof?
Fi Mini is built for everyday outdoor exposure including rain and splashing. Check the product page for the specific water resistance rating.
Does Fi Mini track activity for cats?
Yes. Fi Mini logs activity so you can see how active your cat is over the day and spot changes in their routine.
Can I get an alert if my cat goes missing?
Yes. Fi sends a notification when your cat leaves a designated safe area, and Lost Pet Mode increases location update frequency to help you track them down quickly.
How much does Fi membership cost?
Fi membership starts at $19/month, with longer prepaid terms available at a lower effective monthly rate. The membership page lists current options.
Can I use Fi Mini for both my cat and my dog?
Yes. You can add multiple pets to a single Fi account, each with their own Fi Mini and membership.
Is the Fi app available on iPhone and Android?
