Zeke's cancer, was found in his rear leg, but the Vet was pretty sure that it had metastasized from another part of his body. Most likely his spine. Could it be that Hunter's cancer is the same, in that it is a Metastasis from another area? Management of pain also has it's drawbacks, in that it will make them sick and not want to eat. So anything you can do for Hunter to make him comfortable, without the ill effects of drugs will be the key. All my prayers for the both of you as you travel together down this new road.
