Jellybean's mast cell cancer is unfortunately systemic and in her liver as well. The vets think that with her spleen removed, she can live for another year at least, or more if we are lucky.
Literature shows that chemotherapy isn't very effective.
We might see one more oncology vet for a second opinion, but at this point I think we are going to let Jellybean live out the rest of her days in peace, hope that she can still have a good long life, and treasure our remaining time with her.
Thanks everyone for your support. Jellybean is in good spirits and is as clueless as ever.
As of today she is 14 years and 6 months old.
