There are 40 species of cats and this group is widely distributed. However, they do not exist on Antarctica, Australia, and New Guinea and are missing from the West Indies and many Pacific Islands. They can be found from tropical desert climates up into the boreal forest. They are all carnivorous, but some are adapted to hunting by stealth while some chase their prey over distance. Most are easy to detect with camera traps although some of the forest species are primarily tree-dwelling and therefore less detectable.
