It seems like your friend's cat, Lisa, has given birth to three kittens. In her message, she refers to the kittens as "Junge," which is the German word for offspring or young ones, and she mentions the number 3. So, it appears that there are three new babies. To congratulate her, you can say something like: "That's such wonderful news! Lisa's kittens look so adorable. Congratulations on the new additions to the family. I'm sure they'll bring a lot of joy to you and Lisa."
