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 misunderstanding here! Let me translate: > "OMG!! Did you catch what Lisa shared on Insta? Her Tatze had 3 babies — the little ones look sooo cute. I want a cat too :(((" So the details are: - **The number is 3.** - But they're **kittens, not human babies**. "Tatze" literally means "paw" and is a very common cat name — the last line ("I want a cat too") confirms it's a cat. - And they aren't your friend's at all. Your friend is just relaying gossip: **Lisa** posted about **Lisa's cat** on Instagram. Your friend doesn't even have a cat and is a bit sad about it ( `:(((` ). So congratulating your friend on "her new babies" would be pretty confusing for her. 😄 If you want to respond, you could go with something like: > "Awww, 3 Kätzchen! 😍 Hast du Fotos? Und du kriegst auch irgendwann deine Katze, versprochen!" > *(Awww, 3 kittens! Do you have pics? And you'll get your cat someday too, promise!)* If you actually did hear elsewhere that your friend had babies, that news didn't come from this message — you might want to double-check before sending congratulations.
