Just wanted to let you know that I just heard from the vet and Zoe's surgery went well. The growth was a spleenic mass (actually two--both the size of baseballs). The vet removed Zoe's spleen and the masses and sent the masses off to be biopsied. Zoe will spend the night at the vet's tonight and will hopefully be ready to come home tomorrow morning. The vet expects her to be back to her usual self in about a week. So that's the news for now. Thanks for all your prayers and kind words.
