The African pygmy squirrel is a species of rodent in the family Sciuridae. It is monotypic within the genus Myosciurus. It is found in tropical rainforests in Cameroon, the Republic of the Congo, Equatorial Guinea, and Gabon. It is not considered threatened, but likely declines locally due to habitat loss. Together with the least pygmy squirrel of Asia, the African pygmy squirrel is the world's smallest squirrel measuring about 12–14 cm (4.7–5.5 in) in total length and just 15–18 g (0.53–0.63 oz) in weight, which is less than a typical house mouse.

The island fox is a small fox that is native to six of the eight Channel Islands of California. There are six subspecies, each unique to the island it lives on, reflecting its evolutionary history. Island foxes are generally docile, show little fear of humans, and are easily tamed. Island foxes played an important role in the spiritual lives of native Channel Islanders. Island foxes have been likely semi-domesticated as pets, used as pelts, or for other functions, like pest control.
