hi everyone i came to this forum hoping to find some answers, i am a first time owner of 2 female guinea pigs, in the picture is lilly, i bought her and her sister agnes about four weeks ago at a pet store and am unsure if she is pregnant or not, ive been searching for answers every where and can't seem to find any definite answer without taking her to a vet. If I cant get an answer i will take her but dont want to pay too much to see one. Ok So basically when i got her she was hesitant to be picked up or petted or anything and after some patience she now happily gets held and petted. She has put on a lot of weight very quickly and has two bulging lumps on either side of her lower belly, she has widened hips and erect teets, she eats guinea pig mixture consisting of pellets and other mix daily, also eats carrots and apples, straw and hay and drinks plenty of water. When fed she will eat and drink constantly so that could also be a sign. Could anyone help me please to tell me if she is actually pregnant? thankyou.
