Meet the Fi Mini, our sleekest GPS tracker yet, built to go with either your dog or cat!
Light and flexible, it easily attaches to most collar bands or harnesses, giving you the freedom to style it your way while staying securely connected to your pet.
The Fi Mini is designed with smaller dogs and cats in mind. We engineered the Fi Mini to be significantly lighter than the Series 3+, while keeping all the powerful technology that enables real-time tracking and escape detection.
The Fi Mini is our first and only cat-compatible tracker designed for indoor and outdoor explorers. The Fi experience for cats is slightly different, and we break it all down for you in the Fi for Cats article.

FAQs
Q: My Fi Mini arrived. How do I get started?
A: To kick things off with your Fi Mini, check out the Activate & Attach Your Fi Mini article for quick setup steps.
Q: When am I charged for my membership?
A: Your membership is charged after you activate your Fi Mini. If you are adding the Fi Mini to a pet that already has an active Fi Membership, there is no new membership charge.
Q: How do I attach the Fi Mini to a collar band or harness?
A: To attach your Fi Mini to your pet's collar or harness, follow along with this quick video for step-by-step guidance. Please note that we do not recommend using more than one attachment on a collar at a time. This can put extra strain on the strap or soft case, leading the attachment to potentially stretch more than intended.
Q: Can I attach the Fi Mini to a Fi Collar band?
A: No. The Fi Collar band is designed for use with Series 3 or Series 3+ products only. Due to the magnetic locking system, it's not compatible with the Fi Mini.
Q: Do I need to remove the Fi Mini Tracker from my pet's collar or harness to charge it?
A: Yes. Since the Soft Case and Strap don't have a cutout for the USB-C charging port, you'll need to remove the Fi Mini Tracker when it's time to recharge. For the smoothest experience, we recommend just sliding the tracker out of the Soft Case or Strap. This will make the charging experience quick and easy.
Q: If I have a Fi Base, can I use it with the Fi Mini?
A: The Series 3 Base can connect to your Fi Mini via Bluetooth to further enhance tracking and battery life at home. However, the Fi Mini is not compatible with any Fi Base for charging.
