It's possible that you're trying to say:
* "Little kitty is...": "Little kitty" translates to "Gatito pequeño" in Spanish. You could complete the sentence with a description of the kitten, like "Gatito pequeño es lindo" (Little kitty is cute).
* "I like kitty...": "I like" translates to "Me gusta" and "kitty" stays the same. So you'd say "Me gusta kitty".
To get a more accurate translation, please clarify what you're trying to say. 😊
