The word "Muizen" seems to be Dutch or a proper noun. If you're referring to "Muizen" as a location or proper name, it would remain as "Muizen" in Italian as proper nouns typically don't translate. However, if you meant to translate "muizen" as in the informal plural of "mouse" in Dutch ("mice" in English), the Italian word for "mice" is "topi". Could you clarify what you mean by "Muizen"?
