This is the best tracker I have ever come across , very light and as its distributed into the whole collar so not off set weight my kitten does not ever realise she has it on , when I tried the trackers that fit onto the collar she hated it !!! This one is so comfy and she doesn’t even know it’s on . So easy to keep tabs on your kitty and being able to connect to your phones hotspot enabling it to go mobile to find your car further afield out side of your house wifi is just magical . Never again will I have a sleepless night not knowing where my kitten is . Well worth the money for peace of mind . Absolutely love it 😍
