Looks like there might be a little mix-up here! 😊 Your friend isn't talking about human babies at all—she's talking about **kittens**! Here's the translation: > "Omg!! Did you hear what Lisa shared on Insta? Her **Tatze** had **3 babies** (kittens) - the little ones look soooo cute. I want a cat too :((("" A few notes: - **"Tatze"** literally means "paw" in German, but here it's almost certainly the name of Lisa's **cat**. - **"Junge"** in this context means the young/babies of an animal (a litter). - Combined with "Ich will auch eine Katze" ("I want a cat too"), it's clear these are kittens, not human babies. So the answer to your question: there are **3 kittens**! 🐱 You might want to double-check with your friend before congratulating "her" on the babies, though—it sounds like the kittens belong to **Lisa**, not the friend who texted you. So you'd be congratulating Lisa, or just sharing in your friend's excitement about the adorable new kittens! 😄
