Hi, I have a 17 year old cat, she was diagnosed with kidney failure in may, the vets tried fluids via a drip and tablets but her they didn't help and she got worse, the vets implied she would only have a couple of weeks left but four months on she is still here. 
I took her for a check up last week and asked the vet how long she thought she would have, the vet didn't know but said I would know when it's her time as she would go off her legs. Anyway this week she seems to have gone slightly downhill, sitting in corners and smells dreadful, not just from her mouth but from her whole body, she is still eating and weeing (everywhere) I'm so worried, we are on holiday later this week and have a friend coming in a couple of times a day to feed etc.
Does anyone have any advice do you think these new symptoms are a sign the end is in sight?
