Took it to the vet twice. She is really skinny, runny poop and won't eat anything but tiny pieces of bread. I've tried oatmeal, boiled eggs and cat food. I have water that has electrolytes and vitamins in it and have gotten her to drink some. She just lays there with her eyes closed. Vet gave her antibiotic shots, but she just keeps getting worse. Any ideas? Vet has no idea what is wrong with her.
