The ultimate in spa relaxation isn’t a new treatment — it’s adding kittens. Best Friends Animal Society is bringing kitties to help take the de-stressing to a whole new level at Aveda Lifestyle Salon (456 W. Broadway) on Saturday, April 9. From noon to 5 p.m., spa-goers can get free one-on-one cuddle time with kittens and fully grown cats. And if you like your new partner in Zen, all of the cats are fixed, microchipped and adoptable for a $10 fee. Find all the details here.
