Based on the message, your friend is talking about Lisa's cat (Tatze means "paw" in German, used here as a nickname for a cat) having 3 kittens - not about your friend having babies herself! The message translates to: "OMG!! Did you see what Lisa shared on Insta? Her kitty had 3 babies - the little ones look sooo cute. I want a cat too :(((" So this is about Lisa's cat having 3 kittens, not about your friend having human babies. You might want to double-check before sending congratulations!
