Yes, modern GPS trackers are designed to be safe for continuous wear. They use low-power radio frequencies that have been tested for safety and typically emit significantly less radiation than a cell phone. However, it's important to ensure the tracker is properly fitted - you should be able to fit two fingers between the collar and your pet's neck. Regularly check for any signs of irritation or discomfort, especially when first introducing the tracker. Most pets quickly adapt to wearing tracking devices, but monitor your individual pet's reaction and consult your veterinarian if you have specific health concerns.

GPS accuracy varies based on several factors. In optimal conditions with a clear view of the sky, most GPS trackers are accurate within 10-30 feet. However, accuracy can decrease in areas with tall buildings, dense tree cover, or when your pet is indoors. Many modern trackers use multiple technologies simultaneously (GPS, Wi-Fi positioning, cellular triangulation) to improve accuracy in challenging environments. For the most precise location data, look for trackers that update frequently (every 15-60 seconds) and use multiple positioning technologies. Real-world testing in your specific area is the best way to gauge expected performance.

Clip-on trackers can be excellent for outdoor cats, particularly in urban and suburban areas with good network coverage. Their lightweight design is ideal for cats, who are more sensitive to collar weight than dogs. However, effectiveness depends heavily on your location. In areas with many users of the same tracking network (like Tile or Apple's Find My), clip-on trackers work remarkably well. In rural areas with fewer network participants, a GPS tracker might be more reliable. For cats that roam beyond your immediate neighborhood, consider a tracker specifically designed for felines with appropriate weight and size specifications.

Most quality trackers are designed to be durable and secure, but accidents happen. For GPS collars, ensure you purchase from companies with good warranty policies - many offer 1-year limited warranties that cover manufacturing defects. Some premium brands like Fi offer replacement programs for lost devices (often for an additional fee). Clip-on trackers are generally less expensive to replace. To prevent loss, regularly check attachment points and consider using secondary security clips. For water damage concerns, look for devices with high waterproof ratings (IP67 or IP68). Always register your device with the manufacturer and keep proof of purchase in case you need to make a warranty claim.

Yes, most GPS trackers require cellular service to transmit location data to your smartphone. The tracker itself uses satellites to determine location, but then uses cellular networks (like those from AT&T, T-Mobile, or Verizon) to send that information to the app on your phone. This is why monthly subscriptions are necessary - they cover the cellular data costs. Some specialized GPS trackers use satellite networks directly (like SPOT devices), but these are typically more expensive and have higher subscription costs. Before purchasing, check which cellular networks the tracker uses and ensure they have good coverage in your area.

Most tracking services allow you to monitor multiple pets, but policies vary. Some companies include multiple pets in a single subscription, while others charge per device. For example, Fi includes up to 3 pets in their premium plan, while Whistle charges a reduced rate for additional pets on the same account. Clip-on trackers like Tile typically don't have subscription fees for basic tracking, so you can track as many as you want without additional monthly costs. When comparing options, check the multi-pet policies and calculate the total cost for all your animals. Also consider whether the app interface makes it easy to switch between pets and if you can see all their locations on a single map.

Update speed varies significantly between technologies. GPS trackers typically provide updates every 15 seconds to 5 minutes when in active tracking mode, giving you near real-time information about your pet's location and movement. Clip-on trackers work differently - they only provide updates when your pet comes within range of a network user's device. This could be minutes or hours depending on your location and how many people use the same tracking network in your area. Some clip-on services offer premium features that notify you immediately when your pet's location is updated. For the fastest response in an emergency situation, GPS trackers with frequent update intervals are generally more reliable.
