This is my other gerbil, whom I was TOLD was female, turns out my little Opal is a BOY XD He is the sweet and loving daddy of my first gerbil litter and is taking very good care of his pups with Kaluah. I left him in the cage since it's her first litter, and with 8 little bodies shes's bound to need some help. When the pups are older and the new set is on it's way, he will be separated with his boy pups
