The term "weretiger" usually refers to a mythical creature that can transform between human and tiger form. However, there are several other words that can be used to describe similar beings. For instance, the term "therianthrope" refers to anyone who can shape-shift between two or more forms, including those of animals. Another word that is often used is "lycanthrope," which specifically refers to someone who can transform into a wolf. Similarly, "werecat" is a term used to describe someone who can transform into a domestic or wildcat instead of a tiger. "Shape-shifter" is another common term that can be used as a synonym for weretiger.
