Cat

One of humanity's most successful domesticated companions, domestic cats are small, agile carnivores originating from the Near Eastern wildcat (Felis silvestris lybica) domesticated approximately 10,000 years ago. With over 70 recognized breeds, cats retain strong predatory instincts and have colonized virtually every terrestrial environment on Earth. They are the world's most popular pet, with an estimated 600 million kept worldwide.

koala

Iconic marsupial of eastern and southeastern Australia, koalas weigh up to 15 kg and spend up to 22 hours daily sleeping to conserve energy from their low-calorie eucalyptus leaf diet. Highly specialized to process toxic eucalyptus compounds that would kill most other mammals, they have gut microbiomes uniquely adapted for detoxification. Listed as Endangered in 2022, with populations decimated by chlamydia disease, habitat clearing, and climate change.
