They gave her a different medicine yesterday while she was at the vets to help settle her stomach and it made a huge difference!
Her poo is still very runny but shes isnt going as often and it is no longer black/tarry looking and very little blood. She isnt really eating the I/d anymore so the vet told me to try boiled chicken and rice. She ate that like she was starving, im only offering her small amounts at a time. She is back at the vets today just for supervision. They also took her catheter out of her leg. All of her test have came back ok, so they are thinking she just ate something. :/ She is not one to eat anything but her food so Im still baffled. Thank you all for the prayers, they worked!
