It seems you're using a mix of Tagalog and English to communicate with your friend. Based on the sentence: "Ang pusa ko ay kakapanganak lang nang limang kuting." Here's a translation: "My cat is just about to give birth to five kittens." So, there are 5 babies (kittens), not human babies. If you want to congratulate her on the expected arrival of the kittens, you can say something like: "Masayang-masaya ka dito? Ang mga anak mong pusa na mag-iiwan din ng isang bagay na ganap na kalakip sa pagkuha nito!" (It's like saying: "You're going to be a proud mom soon?" or "You're expecting a lovely addition to the family soon!")
