A typical treatment involves the insertion of very fine, sterile, single-time-use needles into designated pressure points on the body.
Curious what a needle looks like? Check out this picture I took and have included for you to see so you can understand what I mean when I say "very thin."
Let me break down the picture for you: On the left is a black-eyed pea bean; Above the two acu-needles, the ones with the handles, and below the mechanical pencil is a sewing needle; Below the two acu-needles is a whisker that one of my poor little kitties lost during a brawl with his brother (also a kitty). As you can see, the acu-needles are just as thin, if not thinner!, than a cat whisker!!
