It is really hard to say. Some cats respond to fluid therapy and some don't. If the vet is really concerned about her kidney values then they are probably really elevated and it is hard to say if she will do well on fluids or not. If you take her home and she doesn't get any fluids she will surely pass away. So at least at the veterinary clinic she is getting a chance and if her body can it will pull her through and may buy you some time with her.Thanks. Do you think she has a chance? I am trying to prepare myself for what happens. I lost my other old cat in 1996 when his kidneys shut down. I have felt guilty ever since leaving him in a cage at the vets instead of having him home. I just know he felt we deserted him. If I knew she wouldn't live for sure I would go get her and let her die here. I don't want her to die feeling lonely. I called this particular vet because he is the one everyone has said is the best. It was worth driving an hour each way to get her the best care possible. Our local vets don't have the equipment to handle these things.
I know it is hard to have them pass away alone but kidney failure is a terrible way to pass away and can take several days for her to succumb on her own. If you do take her home I would highly recommend having someone out to euthanize her at your home so she doesn't suffer as her body shuts down. I think if you called the vet and asked him to tell you if he thinks she has an honest chance of pulling through or not that would give you an idea of what to do. You should tell him that if he thinks she is going to pass that you prefer to have her at home and euthanized than to be alone and die in the hospital. I can even talk to DH if you decide you want to bring her home and maybe we could meet you this weekend. I have had several pets euthanized at home and it is always much nicer to have them in a familiar place when they go.
You could give her 24 hours on fluids and they might just re run her BUN/Creatanine levels to see if she is making any improvements too?
