As a result of the acquisition, the Whistle platform is being shut down and its pet tracking devices will stop working on August 31st, 2025. Existing Whistle customers can get a free Tractive tracker as a replacement, while remaining subscriptions “will transfer to your new Tractive device,” according to the Tractive website. Image: TractiveTractive is also honoring remaining Whistle plans but will be adding the remaining time to new Tractive subscriptions. The company’s Basic subscription plan starts at $108 if you subscribe for just one year, but a two year plan is discounted to $144. Although remaining Whistle subscriptions are being honored, Whistle device warranties are not.
