This is what I might call a cat fancy dictionary. There are numerous words that are used in the cat fancy that are unknown to most of us outside. They might relate to health, genetics, breeding and cat showing, for example. Or they are commonly used words but have a particular meaning within the cat fancy community. When you read the information that is on this site it might pay dividends to return here if the meaning of a word needs clarifying. This will be an expanding page as I return to it myself to add new words. They are listed alphabetically with a contents section for ease of reference. Finally, it could be much longer but I have deliberately limited it.
