Cats are everywhere in Tulum, Mexico. These gatos sleep during the day and hunt at night. Even when asleep they can wake instantly, move into a predatory stance, run up a tree trunk to safety amid sea grape leaves. They are used to people, allow themselves to be stroked, take food offerings when they can get them. They have no collars, no tags. Cats have perfected the art of being asleep and awake at the same time, the art of living in the moment that humans at Yoga Shala work to achieve on their mats, doing deep breathing exercises, twisting their limbs into pretzels, listening to the voice of a guru who is where they want to be. Studying cats is my plan of the day. The ability to take cat naps is worth all the study I can give it.
