Oh, wow! Have you seen what Lisa posted on Instagram? Her cat had 3 kittens, and they are sooo cute! I want a cat too :( It sounds like your friend congratulated her friend Lisa because Lisa's cat recently had 3 adorable kittens. The kittens look incredibly cute, and seeing them has made your friend want a cat of her own. "Tatze" in German translates to "paw," which is not what she meant - it seems she misspoke and meant "cat" instead. Overall, it seems your friend is excited about the new kittens and wants one too.
