Juni's nick-names are in Romanian, so, I'll provide a translation and pronounciation hints.
Junitsa - just a diminutive
Junitsoaea - a diminutive + (how can I call it? ) the antonym for diminutive
Dulcheatsa - jelly
Spurcachiune - this is very dificult to translate. Ignorant people call this name animals that eat "not clean food", meaning, sometimes even dead animals. Cows, eat "clean food" e.g. But this is only the original meaning of the word. It lost it and became just an adjective with one of the meanings of Bad.
When I call her this name, I mean something else - that she got me warpped around her paw, and does whatever she wants with me.
Juneasa - sounds more formal
Juneasa Vasilevna - sounds VERY formal in Russian
Labutsa - tootsie
Coditsa - little tail
Vargata - stripey
Dracushor - little devil
Tundurlitsa - no idea what this means
Carolina (my sister) calls her Zahar Dulce (Sweet Sugar) and Printsesa ( ).
My brother calls her - Capusha - tic (blood-sucking insect), beause when he spoils her, she gets very strange and almost want to get into his mouth and under skin to get petted more.
I have a longer list, but, I don't want tou to get bored - just silly names.
