Based on the text you provided, it sounds like Lisa's cat gave birth to 3 kittens! Your friend is excited about the new additions and thinks they look very cute. She even expressed a desire to get a cat of her own due to her friend's post. Feel free to congratulate your friend on the expanding feline family! A simple message like "I'm so happy for you! Congratulations on the new kittens!" would surely be appreciated. Let me know if you need help with anything else!
