I adopted a 14 year old hospice cat with chronic kidney disease and high blood pressure. Over the past couple of weeks I've noticed she has feces collecting around her vulva. I had her groomed and shaved there but the problem persists. I am doing my best to keep the area clean but today I noticed some blood. A vet friend of mine suspects a fistula, permitted feces to be excreted through her vagina. The remedy is surgery. We have an appointment Monday. Does anyone know if she can handle anesthesia with her issues? Thanks.
