long story short, I purchased my guinea pig from someone on Facebook, she was already pregnant when we brought her to our home. I don't know exactly how far along she is but she is very large and I can see lots of movement in her belly. She has not been drinking hardly any water today and doesn't want any of her treats (carrots,peppers) all she has been doing is hanging out by the hay rack eating a couple pieces here and there. Is this normal? Should I take her to a vet if this continues?
