OMG! My sister's Guinea Pig left a present in her cage for us, and it did not look human. My mother and sister took her and the weird thing to the vet, and nobody knew what it was. a few days later, after they examined it in the lab, they found it was Cancer that fell out of her Uterus. We don't know what to do! My sister's Guinea Pig has Cancer! :(
Man, thats a real bummer, my mom had cancer, but the doctor killed it all. :D
