The word Nippur comes from an old sacred city in Persia, that according to Persian Mythology existed since the beginning of the times. I considered the name as a perfect one for my kitty. Later when the moment came to register my cattery in Cat Fanciers' Association I tried to combine different names in a single word and finally I decided to combine the name of Nippur and the first letters of my name Enna and so in a natural way a got the word NIPPUREN. Nippuren is a trademark and also registered in CFA. FIFE and TICA.
