Hi. I'm trying to attach sensors to my cats. They don't appreciate it as much as I do. What have y'all done to attach sensors to your pets?

I have used the Ti system (134 KHz) with good success. I used antenna coils of various sizes up to about 12 inches to increase range, usually printed on a large PCB, but wire coils worked fine too. They definitely need to be tuned to the correct frequency. These could read a standard tag out to about 8 inches from the antenna, so the pet wouldn't need to go through the antenna - it just would need to be within 8 inches. Incidentally, there are online calculators that will calculate inductance versus geometry of printed coils.
