Smell influences food intake in cats, according to a new study.

Does Your Cat Always Leave Behind a Half-Full Bowl of Food? New Research Points to Why Our Furry Friends Can Be Such Picky Eaters

A new study suggests that domestic cats get bored of monotonous meals. Switching up their food—or even just nearby scents—could help them join the clean plate club

Adult emperor penguins have waterproof feathers. But they replace all of them every year during their catastrophic molt, which makes them vulnerable.

As Their Antarctic Habitat Melts Away, Emperor Penguins Are Now Considered an Endangered Species

The International Union for Conservation of Nature predicts that the birds’ population could be cut in half by the 2080s. The organization also changed the statuses of Antarctic fur seals and southern elephant seals
