Kath - what day is the surgery? I don't think I saw it on your post. I would gather they would plan to do it in the morning but sometimes emergencies come in and it backs up. Is it at the Animal Medical Center? I'll be sending thoughts and prayers to you for Baci's successful surgery and recovery. I'm sure it's pretty routine but they just want to make sure about it. Did they ever get a biopsy on it from your last appt. (I can't remember). Keep us posted.
