I need your help. I want to congratulate my friend on her new babies, but how many are there? Here's what she said: Omg!! hast du mittbekommen was Lisa auf Insta geteilt hat? Ihre Tatze hat 3 Junge bekommen - die kleinen sehen sooo süß aus. Ich will auch eine Katze :(((

Careful—I think there's a mix-up here! Let me translate what your friend wrote: > "Omg!! Did you see what Lisa shared on Insta? Her **Tatze** (cat) had 3 babies — the little ones look soooo cute. I want a cat too :(((" So a few things to clarify: 1. **These are kittens, not human babies.** "Tatze" literally means "paw," but here it's the name of a **cat**. The cat had **3 kittens** 🐱 2. **They aren't your friend's babies, and not even Lisa's directly** — they're Lisa's cat's kittens. Your friend saw this on **Lisa's Instagram**. 3. Your friend is just gushing about how cute they are and saying she wishes she had a cat too. So before you send a congratulations, you might want to double-check the situation 😄 If you *did* want to react, the right move would be to comment on **Lisa's** post about her cat's kittens — not to congratulate your friend, who didn't have any babies (human or feline)! Want me to help you write a cute reply to your friend, or a comment for Lisa's post?
