Surely then a stalker just needs to be bright enough to make up a story like "I put it into my bag or wallet when I go out, and since I only have one tracker I often move it between them depending on if I have much cash." rather than "I got it for my cat"? That story took under a minute to come up with, I imagine there are even smoother ones a stalker could think of with 20mins effort.

Or at the expense of making it a little bigger, superglue something like a usb stick and you've always got an excuse to have it in your pocket until you "lose" it. Hell, isn't not wanting to lose a coat that you claim to often leave places a good enough reason to have one in your pocket?
