If Gizmo hasn't eaten in 3 or more days, she is at risk of developing serious liver related complications. At this point in time, she needs to be examined by your veterinarian. Blood work should be submitted to assess major organ function. Bring the medication your gave her (or the package it came in) to your vet for examination as well. She may require hospitalization and supportive care until she is eating on her own. Discuss payment plans with your vet as well as alternative financing options such as Care Credit (www.carecredit.com). You may also seek financial assistance through Red Rover (www.redrover.org).
