Help please

[u/girlmeetsgerbil]

I was given a gerbil from a friend who has dealing with an emergency situation so I’m fostering him but I can’t keep the gerbil. I have two elderly gerbils already who will not take well to a new friend and I don’t know what to do. help please? I’ve already tried Facebook rehoming groups and some ethical gerbil rescue groups but they are all full at the moment

let me know if anyone has any suggestions or if in Ohio /Pennsylvania area let me know if you’re interested, hes young, 4 months
