My father's cat, Squeaky, is under veterinary care right now, but the vet is stumped. Squeaky went to the E.R. two days ago with fever, very dry stool, trace of blood in her urine, nauseous, constipated, lethargic and no appetite. Her fever was only brought down today, but she is now completely lethargic and hasn't eaten for days. All of the tests they've run have come back negative. The vet actually took Squeaky home with her tonight, because she's afraid she won't make it. Has anyone had a cat with similar symptoms? Any advice, no matter how obscure, is much appreciated, as this is something the vet has never seen before. Thank you in advance.
