Well I've been trying to keep track of my piggies weight to make sure they're healthy and in 3 weeks my peruvian, Jinx gained 285 grams! But Fizgig, my other piggy only gained 28 grams.... Jinx originally weighed in at 650 grams and is now 935. Fizgig was 765 grams and is now 793. Is this normal or could there be something wrong with Fizgig?
