Congratulations to your friend on her new babies! From the message you've provided, it seems like she has 3 new babies (Junge is a masculine noun, but can be used for both genders in this context, and in German, the number 3 is a neuter noun, which is why they used "drei" instead of "drei"). The babies seem to be kittens as they are referred to as "die kleinen" (the little ones) and "süß" (cute) which is often used to describe animals, and she's jealous of her friend Lisa who shared the news on Instagram. A possible translation of the message is: OMG! Have you seen what Lisa shared on Instagram? Her cat has had 3 kittens - they look sooo cute. I also want a cat :(((
