That's a fun one! "Pusa" is the Filipino word for "cat," not "baby." So, your friend is saying that her cat has just given birth to... five kittens! In Filipino, "kakapanganak" is a verb that means "has given birth to." So, the correct translation is: "My cat has just given birth to five kittens." So, no actual human babies there. Nevertheless, you can still congratulate your friend on the new additions to her family... with a playful nod to her feline friends!
