The chapter ’Da Kittehz’ focusses on semiotics and syntax with examples from LOLcats and LOLspeak. The section on semiotics shows us the difference between image macros (memes) and vernacular photos, both of which are present in the cat-related digital spaces. The chapter continues with a description of LOLspeak as a special internet language variety (SILV) in relation to pidgins, play language, and ludlings. Based on the methods of the existing studies on LOLspeak, it analyses the spelling, vocabulary, and grammar of LOLspeak. The final section shows us more cat-related language varieties that have developed in the cat-related digital spaces on the Internet, like Hambspeak and other cat-inspired idiolects.
