The term CAT ENDANGERED refers to three species of cats that are endangered: the TIGER (5 letters), CHEETAH (7 letters) and NENE (4 letters). Tigers are the largest of the big cats, and their population has been declining due to poaching and habitat loss. Cheetahs are the fastest land animals, but their numbers have been reduced due to hunting and loss of habitat. The NENE is a species of goose native to Hawaii, and its population has been threatened by introduced predators and habitat destruction. All three of these species are in danger of extinction, and conservation efforts are needed to protect them.
