芬兰采购需求：背包

I'm looking to source a lightweight GPS tracker specifically designed for tracking cats in forested areas. The device should be compact, easy to attach to a collar, and able to withstand outdoor conditions. I'm particularly interested in features like long battery life, real-time tracking capabilities, and accuracy in dense vegetation. It's essential that the tracker can provide alerts or notifications if my cat strays too far from a designated area. Additionally, I'd like to know about the available options regarding connectivity—whether it uses cellular data, Bluetooth, or other technologies for location tracking. Durability is also a key factor; it should be water-resistant and able to handle rough outdoor environments. Please provide any relevant specifications, estimated pricing, and lead times for availability. Looking forward to your detailed response!
