The term "cataholic" is a blend of two words: "cat" and "holic". The word "cat" originates from the Old English word "catt", which is believed to be derived from the Late Latin word "cattus". It is also related to the Old Norse word "köttur" and the German word "Katze". "Holic" is a short form of "holicism", which comes from the word "holic" meaning addiction or dependence. The suffix "-holic" is commonly used in English to describe a person who is excessively or obsessively interested in something. In this case, "cataholic" refers to a person who is a big fan or lover of cats, exhibiting a strong attachment or addiction to them.
