Happy to help! But there's an important mix-up to point out before you send any congratulations. π Here's what the message actually says: > "Omg!! Did you see what Lisa shared on Insta? Her **Tatze** had 3 babies β the little ones look sooo cute. I want a cat too :(((" A few key things: 1. **It's not about your friend's babies.** Your friend is talking about someone named **Lisa**. 2. **It's not even about human babies β it's kittens!** "Tatze" literally means "paw" in German, but here it's almost certainly the **name of Lisa's cat**. The clues are "Junge bekommen" (which is how you describe an animal giving birth) and the last line, "I want a cat too" (*Ich will auch eine Katze*). So the situation is: **Lisa's cat had 3 kittens**, and your friend is gushing about how cute they are and saying she wishes she had a cat too. So before you congratulate your friend on "new babies," you might want to double-check β unless you'd like to say something like *"Aww, the kittens are adorable!"* π± Or if you genuinely thought your friend just had babies, this message isn't announcing that at all! Would you like help writing a cute reply in German?
