my guinea pig, pepperoni (about 3mo), is a rather quiet guy. he tends to purr when i pet him, but he has only squeaked a few times. when he tries to squeak its very strained and quiet. as far as i know he is rather healthy and eats his food and hay & drinks water. he's generally happy. i have another guinea pig, butter, and he's eats just as much as pepperoni and drinks the same amount of water, but butter squeaks on a daily basis. ive had guinea pigs before pepperoni and butter, so i know how things works and what squeaks sound like. butter is all good, but i dont really know what's up with pepperoni. please help! thanks
