The yellow you are seeing is stomach acid, not stomach lining. After spay surgery, you can see vomiting and anorexia; in fact, vomiting is a common post-anesthesia complication. Vomiting once or twice the night after surgery is normal, but if Domino has vomited more than that or the vomiting persists through the night, you need to contact your vet immediately as she will need medication to stop the vomiting.

    Vomiting and not wanting to eat can be common within 24 hours of surgery and anesthesia. If it has been longer than that, then I would have her checked tinmakensure the incision is healing correctly and there is no sign of an infection or something unrelated.

    While vomiting can be seen following anesthesia 9 times in 4 hours seems excessive and I would be concerned about dehydration. I would recommend either contacting your vet or seeing an emergency veterinarian for an exam. They could also give Molly anti-nausea medication.
