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

Based on your friend's message, there are **3 babies**! 🐱 Here's the translation of what she said: "Omg!! Did you see what Lisa shared on Insta? Her cat had 3 babies — the little ones look sooo cute. I want a cat too :(((" So to clarify: these aren't your friend's babies — they're **kittens** that belong to **Lisa's cat** (which your friend saw on Instagram). Your friend is just excited about them and wishes she had a cat too! 😊 You might want to congratulate Lisa on her cat's 3 new kittens, or simply gush about the cute kittens with your friend!
