Okay, let's break this down: Ang pusa ko - My cat ay kakapanganak lang - just gave birth nang limang kuting - to five kittens So based on this, it seems that the friend's cat just had 5 kittens. To congratulate her, I could say: "Maligayang pagbati sa limang bagong kuting! Masaya akong malaman na ang pusa mo ay nagkaroon ng limang malusog na kuting. Sana'y lumaki silang malakas at masaya!" Which translates to: "Congratulations on the five new kittens! I'm happy to hear your cat had five healthy kittens. I hope they grow up strong and happy!"
