My 18 year old cat has been diagnosed with this condition and we've been treating her as directed by our vet. One of the symptoms that she presented with was excessive water consumption. The vet gave her a steroid injection and we've been giving her the prescribed meds daily, yet she's still drinking more than normal. Otherwise she's eating fine and sleeping! (Her usual activities!) Does anyone have experience of this condition in their cat? Should she have reduced her water intake by now or is this a symptom which will continue? She's been having medicine for the past week only. She goes back to the vet in 3 weeks for another steroid jag. Many thanks in advance!
