Based on the message, your friend is talking about Lisa's cat (Tatze means "paw" in German, often used as a nickname for cats) who had 3 kittens! The message translates to: "OMG!! Did you see what Lisa shared on Insta? Her paw (cat) had 3 babies - the little ones look sooo cute. I want a cat too :(((" So this is about 3 baby kittens, not human babies. Your friend seems to be excited about Lisa's cat having kittens and wishes she had a cat of her own.
