Saint Louis Zoo on Instagram: "Turn up your volume to hear these cubs roar! 🐾🔊 Amur leopard cubs Vasilisa (Vasa) and Domovoi are 3 months old and growing fast! Just like their parents, this pair is especially vocal while playing, bonding and eating. Their personalities really shine at feeding time when Vasa dives into her food and Domovoi stays close to mom. Keep your eyes peeled. 👀 You might spot this trio in Big Cat Country very soon…"
