Surprise Baby

Welcome to the forum. Congradulations on your babies and that Momma is ok. I have never had babies, but there is alot of members who can help with babies. I know also there is past threads that deal with raising babies.
Good luck.

Congratulations! Guinea pig babies are so much fun, I just love them. What kind of pellets are you feeding them? They need to be eating a high qulaity alfalfa-based pellet, like Kleenmamas, Oxbow or Mazuri.
If the baby is a boy (you can figure it out by looking here: https://www.cavyspirit.com/sexing.htm) he needs to be seperated from mom at 3 weeks old.
I almost wish I had just come upon Holly's babies when she had hers. Instead I found out a week before she gave birth, and that was pretty much the most stressful week of my life. lol

edit: Some advice I would give you is try to pick Lisa Marie up as much as possible to get her comfortable with the idea that you're not going to eat her. It'll most likely help her be a much calmer guinea pig in the long run.
