Did you know that your body cannot fully break down the tough outer shell of sunflower seeds?

While you may find it challenging to digest sunflower seeds, squirrels face a similar dilemma. Squirrels have a unique digestive system that allows them to efficiently process a variety of foods, including nuts and seeds. However, the tough outer shell of sunflower seeds poses a challenge for their digestion process.

Squirrels have a specialized tooth structure that allows them to crack open the shells, but they cannot fully break them down. As a result, the nutrient-rich interior of the seed remains inaccessible to their digestive system. Despite this limitation, squirrels have evolved to efficiently extract as much nutrition as possible from the sunflower seeds they consume, maximizing their nutrient absorption for energy and survival.

Potential Health Risks for Squirrels Eating Sunflower Seeds
