Can I call my cats mon petite Cherie And what is it's meaning?

Yes, you can call your cats "mon petite chérie," which translates from French to "my little darling" in English. It's a term of endearment that conveys affection and love. Just be aware that "petite" is the feminine form, so it's best used for a female cat. If you have a male cat, you might want to say "mon petit chéri."
