How do your squirrels eat, mine eat upside down

How can squirrels swallow upside down?

At first the thought of swallowing while upside down seems impossible - many people think that food just sort of 'drops' down into the stomach. In reality, food is actually pushed toward the stomach through the esophagus, a muscular tube leading to the stomach. Once food or water reaches the end of the esophagus, a valve called a sphincter closes so it can't come back up.

A lot of squirrel territory is the vertical, navigating up and down the trunks of a trees. They find a seed or nut on the ground and run to a tree trunk to eat out of the view of predators. Because they have the treat in their hands, they only have their feet to secure them to a safe perching area. Fortunately they have well-developed claws in both the front and hind feet to latch on to rough surfaces.

They also can feed comfortable headfirst down trees by swiveling their back ankle joints. Squirrels can maneuver quickly and gracefully thanks to a special adaptation where their ankles, or wrists, articulate. The squirrel may be heading down the trunk but its feet and claws point upward, enabling a good grip on the bark and a speedy dexterous descent.
