Dcat is 21 and had kidney failure since 12.
She got cystitis just over a week ago and the antibiotics for that have caused diarrhoea which started on Friday. Bloods taken last week were ok for her. Vet hoped the injection for the diarrhoea would last a week+. Unfortunately it hasn't and the diarrhoea has started again.
Poor cat is stressed going to vets (been 3 times in last week). If treatment isn't working when do I call it time? We've had dcat since she was 8 weeks old.
