Kidney Disease in Cats: Catching It Early

Chronic kidney disease affects a large share of cats over ten. Symptoms only appear once most function is already lost, which is why screening matters.

Early markers

Increased drinking and urinating, gradual weight loss, and a duller coat. By the time appetite drops and vomiting starts, the disease is advanced.

Screening

Annual bloodwork from about seven years, and twice yearly after ten. The SDMA marker detects loss earlier than creatinine alone.

What slows it

A renal diet with restricted phosphorus is the single most evidence-backed intervention. Blood pressure control and phosphate binders where indicated. Hydration support matters enormously.

Quality of life

Many cats live years after diagnosis. Appetite, weight and hydration are the practical things to track at home.
