Have you ever seen your cat or dog smile at you? And it’s really cute, isn’t it? Similarly, quokkas are an adorable species of animal that always has a smile on their face. The quokka, also known as the short-tailed scrub wallaby, is a tiny and adorable animal that is around the size of a domestic cat. The quokka is a herbivorous, nocturnal species that live on Rottnest Island in numbers ranging from 10,000 to 12,000 individuals.
The sad fact is that quokkas are an endangered species in Australia and they can be seen only on the Rottnest Island. The quokka has gained the title “the world’s happiest animal” due to its friendliness toward humans and its smiling face. Because of their cute appearance and convenient visibility, they have become one of Rottnest Island’s most popular tourist attractions.
