Unfortunately, I do not speak that language so I cannot determine exactly how many kittens her cat had based on that sentence. From context clues, it seems to be talking about a cat that gave birth, but without knowing the language and grammar rules, I cannot reliably parse the specifics. I'd suggest confirming with your friend directly, or asking someone who speaks that language to translate the key parts about how many kittens were born. Knowing the language, an estimate, or range would help me construct an appropriate congratulatory message to your friend. Please let me know if you have any additional details I could use.
