Over at Bored Panda, the staff compiled the way people of different languages call cats. Most languages, it seems, repeat a word three times, like the "kitty kitty kitty" part of the United States version. Some sound pretty similar to that, in fact, such as Poland's "kitschi-ktschi-kitschi."
These are different from those orations sometimes labeled "catcalls," which are usually even less inventive and often far less welcomed by their intended listeners.
Besides it really doesn't matter what language you use; unless there's the sound of food preparation involved, cats don't give much attention to calls in any tongue.
