Kidney Failure in Cats: Knowing When It Is Time

The long slope

Chronic kidney disease is the most common terminal diagnosis in older cats and it usually unfolds over months or years rather than weeks. Cats compensate remarkably well until they suddenly do not. Weight loss, increased drinking, increased urination and a gradually scruffier coat are the early signs, and by the time appetite goes the disease is usually well advanced.

What treatment buys

Prescription renal diets, subcutaneous fluids at home, phosphate binders and appetite stimulants can buy good months and sometimes years. The decision point usually arrives when the fluids stop producing good days, or when the cat begins refusing food despite stimulants. Ask your vet plainly whether you are still buying quality or only quantity.

Weekly weights tell the truth

Weigh weekly on a kitchen or baby scale and write it down. A cat losing steadily over a month is giving you clearer information than any single afternoon of appetite. This record is also the most useful thing you can hand your vet.

At the end

Cats in late kidney failure often become nauseated, dehydrated and withdrawn. Hiding, sitting hunched over the water bowl without drinking, and refusing to be touched are late signs. When those appear together, the conversation is overdue rather than early.
