Sorry Mbtvrepair, flyers and grey squirrels don't mingle. Flyers are nocturnal so they they would rarely encounter grey squirrels in nature. I have 2 overwinter grey squirrels and 3 pet flyers. Every time one of the grey squirrels is on my shoulder she will chase the flyers if they jump on my back. The grey squirrels will bully the flyers if I let them. I don't let them mingle.
Zeuss is in Michigan and needs a forever home with a family. He is 2 years old and is a pet so he is not a candidate for going outside in the trees.
Ella I sure hope you find a home for Zeuss. I know this is killing you.
