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 (kittens) - the little ones look soooo cute. I want a cat too :((("* So to clarify: - These are **kittens** (baby cats), not human babies - They belong to **Lisa's cat** (your friend is talking about Lisa's pet) - Your friend herself doesn't have the babies—she's just excited about them and wants a cat of her own You might want to congratulate **Lisa** on her cat's new kittens! 😊
