Thank you all for your concern about Tom... and the good advice you've given!
Mom says he had a little snack overnight, but he's still very lethargic. He has only one more dose of pain meds, so if he seems even less active after the final one, I'll be asking the vet for more.
My Mom also says that Neighbor B said he'd be bringing a check over later today... I wonder what portion of the bill that will pay.
