One of the correct answers given is "Kucing milikmu makan pasta". What does milik mean? That's a new word for me
It indicates possession.
Awesome. So how is "Kucingmu" different from "Kucing milikmu?"
Exactly the same meaning except one of them is shorter.
Milk = susu
"Kucing kucing kamu makan pasta" seharusnya benar dan tidak terlalu formal
