Congratulations to your friend! In Tagalog, "kakapanganak" means "just gave birth", and "limang kuting" means "five kittens". So, your friend's cat just gave birth to five adorable new kittens! To congratulate your friend, you could say something like: "Huwag kang mag-alala, namimili, at maligayang bati sa limang kuting! (Don't worry, take care, and happy kittens!) Or, more simply: "Maligayang bati sa mga bagong kuting!" I hope that helps!
