@jyokota Bless him. Males only live 2 - 3 years maximum as well, so he maybe older than he looks. Females last around 5 years in the grey squirrel world, but males are usually less than half that. Hope he does okay.
@casablanca - oh, no! My daughter also wondered if Oliver was getting old. I have no idea when Oliver was born, and only noticed him during the pandemic when I was spending so much time in my backyard. Whereas Baby, I know she was born last August and she's been comfortable around me because she's known me since she first left her nest. Oh, dear, I hope Oilver is still around this summer, too,.
Thank you all for your concern for Oliver. I'm worried about him because he's been lethargic these days -- and even when moving about, he seems less energetic. His fur is coming out in chunks, and he scratches a lot. Casablanca said that squirrels lose their fur seasonally and not to worry, so let's hope Oliver is perky again soon.
a lethargic sadness. I really hope he is OK
