The vet called and said all went well and she was up and doing okay. They were going to wait an hour and offer her some food...I left an "Angel´s piggy bag" with them filled with a few goodies for her in case she got hungry.
She said the tumor was encapsulated so that was a good sign. Guess now I just wait for the biopsy results. I pick her up on my way home from work.
Thanks for your support, all. It was a nerve-wracking experience!
