I am part of a family owned pet store, and we had a pregnant guinea-pig, she gave birth to two still borns, and one live, and died in birth. We brought the one live one home, and he was around two ounces. He is now in a My First Home 30x36" cage, and shelf, and is over a pound. I have a question. My guinea pig is not the usual shy and scared of heights. He instead will just run up my moms arm, and sit on her shoulder, etc. Is my pig normal?!?!:?:
