With how good the Whistle Cat Tracker is, it has a real opportunity of becoming the Best GPS Tracker available on Amazon. Instead of just using the cellular network, it also makes use of your home Wi Fi network when your pet is at home. And coming at $130, it can also be considered one of the Best Cat GPS Tracker options available at any price.\r\n\r\nWhy We Like It - Whistle Cat Tracker\r\nThe Whistle Cat Tracker is probably one of the only GPS trackers that have it all, irrespective of the price point. The 20 days of industry-leading long battery life is pretty much a boon for pet owners that don\u2019t have as much free time.\r\n\r\nPerformance\r\nThe range on this thing is pretty impressive. And that is mainly because Whistle Go Explore takes advantage of cellular service and Wi Fi network. And it tracks more things than your average pet activity tracker. But if you need a strictly cellular GPS pet tracker, you can also go for the BARTUN GPS Tracker.\r\nBattery\r\nOn the Go Explore Whistle included a massive battery that lasts more than 20 days. This is better than almost all pet trackers at this range. Even their own Whistle 3 GPS Pet Tracker can\u2019t match that. If you buy this thing, you won\u2019t need to check the battery status everyday, unlike most other trackers.\r\nEase Of Use\r\nThe Whistle app available for cell phones is excellent, to say the least. Location tracking is as easy as toggling a button. And, as expected, it has support for all the advanced activity tracking functionalities the Explore Whistle Go comes with. And you can also set multiple different safe zones \/ safe places on this Whistle tracker. Overall, we can definitely say that this app is better than the one you get on the Weenect 2 Cat Tracker.\r\nDurability\r\nTo keep track of your pet\u2019s daily activity every day, the tracker has to be very durable. And this tracker absolutely is one of the toughest pet trackers available on the market right now. And it even has a safety flashlight built-in (remotely controllable).\r\nValue\r\nEven though it comes with a subscription plan, the overall value of this GPS location tracker is insanely good. Not to mention, with the subscription plan, you also get the option to chat with a vet.\r\nWhistle Cat Tracker Wrap Up\r\nSlightly dodgy customer service aside, the Whistle Cat Tracker is an excellent GPS pet tracker overall. You really can\u2019t get anything substantially better than this, irrespective of the price point.
