Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you today. I do apologize that your question was not answered before. Different experts come online at various times; I just came online, read about your situation, and wanted to help.
Again I do apologize that my colleagues could not aid you sooner. If you would still like assistance, can you tell me:
What medication was given?
Did her vet check her for a cat litter blockage? Did they do any tests?
Has she been showing any retching, gagging, lip licking, drooling, or vomiting?
Can she keep water down?
Are her gums nice and pink (not white/pale)? Moist or sticky?
If you press on her belly, does she have any tensing, tenderness, discomfort, or pain?
Any diarrhea, black stool, or straining to go?
