Some Chicago area zoo animals aren't missing out on Valentine's Day. Brookfield Zoo Chicago officials treated a tiger, bear, leopards, gray seals and a sea lion to heart-shaped enrichment, which provides stimulation that benefits animals’ mental and physical health. Whirl the amur tiger and Kartik the Sloth bear both received got meat inside their “boxes of chocolate." Sasha the amur leopard had to use his sense of smell to find treats inside a flower bouquet-shaped enrichment. Grey seals and California sea lions received “Be Mine” unflavored gelatin, which is an aid for hydration. And lastly Malaya the snow leopard received a “U R Pawsome” candy heart-inspired enrichment with meat hidden inside. Credit: Brookfield Zoo Chicago
