Guinea pig not gaining weight?
So I have two guinea pigs, they are about 6 months old and they are brothers. They live together in a large cage. One is a huge porker and hogs the food, even though there is always plenty for both. The smaller pig I am concerned about, he tends to let the porker dominate and eat like there's no tomorrow. I haven't actually weighed them. I know weight and sizes can vary, should I be calling the vet? I don't want him to die.
