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.

common Atlantic octopus

One of the most studied invertebrates in neuroscience and behavioral biology, common octopuses inhabit rocky reefs and seafloors in tropical and temperate coastal waters globally. Highly intelligent with distributed nervous systems — two-thirds of their 500 million neurons reside in their arms — they demonstrate tool use, problem-solving, and individual personalities. Masters of camouflage, they change skin color and texture in milliseconds. They have three hearts, blue copper-based blood, and extremely short lifespans of 1–2 years.
