Based on the message, it seems like Lisa shared on Instagram that her cat (Tatze) had 3 kittens (Junge). So there are 3 new baby cats. To congratulate the friend, I would say something like: "Ich habe gesehen, dass Lisas Katze 3 Junge bekommen hat! Herzlichen Glückwunsch an Lisa zu den süßen neuen Babys! Ich freue mich, mehr Fotos von den kleinen Kätzchen zu sehen." The key points are: - Lisa's cat (Tatze) had 3 kittens (3 Junge) - Congratulating Lisa on the cute new babies - Excitement to see more photos of the little kittens Let me know if this helps summarize how many new kittens there are and gives an idea for how to congratulate Lisa!
