A bobcat (Lynx rufus) traverses along the Mexican-Texas border. A border wall along the lower Rio Grande in Texas divides nations as well as habitats, hindering daily essential movements of animals in the area. Bobcats would normally cross the border to find mates or catch dinner. The wall also blocks the dailly rounds of ocelots, another member of the cat family.
