Potpie's three-month-old kits wrestle one another as a way to practice their hunting skills. As they play up close to the live cam, you may be able to tell them apart! The males, Aspen and Swifty, are now bigger than sister Aster and even Potpie! Also take a good look at their head shape and where the dark patch of fur is on their lower abdomen. The males have wider and rounder heads, while the females have more pointed, elongated faces. Aster has a tiny, thin line of dark fur on her lower abdomen, while her brothers have a wider patch of dark fur. Potpie still has pronounced nipples.
