My guinea pig Tufty just had her babies! She started making funny squeeks so we dashed over in time to see her give birth to the first baby. She was scared and unsure about what to do so we had to break the bag for her so that the baby could breathe, but after that she was a star, she gave birth to 4 babies in total and has cleaned them all up nicely and didnt need any further help. She's so far passed 3 of the placentas, so one more to go.
Just sorting out some pics of them as the births were happening.
Edit
Have added the pics, the divider in the cage is to keep the male away while she gave birth etc (he had his operation today to remove his bits as well so he's recouperating)
UPDATE here are the original pics and a few more https://www.photobox.co.uk/album/59359591
