i'm totally scared that my guinea pig is overweight. he's fatter than many guinea pigs i've seen, and he's obsessed with eating. even when we let him out to play, he runs around looking for food. he weighs 3 and a half pounds and he's 4 years old....it says an average adult pig should weigh about 2.2 pounds..
is this normal for my piggy?
