I posted in my intro that we adopted two female guinea pigs. Two different people. My kids named the fluffy white one marshmallow. After reading through the board here I'm pretty sure she's pregnant. I'm tossing what the woman said out the door about her not being with a male. I wanted to stick with females this time, we were going to get four, so now waiting to see what happens. Good thing I have extra cage stuff for boys if needed. I'm not sure how pregnant she is, I looked at a lot of pics to try comparing. She's got a good appetite and rests a lot.
