Model input

User/Human
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 :(((

Model response

AI
Just a heads up — these aren't **human** babies! 😄 The message is about **Lisa's cat**, which had **3 kittens**. "Tatze" is a colloquial German word for cat (literally meaning "paw"), and "Junge" here means kittens/young ones. So you'd be congratulating Lisa on her cat's new litter! 🐱
