Kidney disease is common in older pets, especially cats. Early signs include drinking and urinating more, weight loss and a decreased appetite, but many pets show no signs until the disease is advanced.
Bloodwork, urine testing and blood pressure checks help us catch kidney disease early. Treatment may include a prescription kidney diet, fluids, medication and regular monitoring to help your pet feel well for longer.
How Kidney Disease Is Diagnosed in Dogs and Cats
Diagnosing kidney disease usually involves several tests that work together to show how well the kidneys are filtering waste and holding on to water and protein:
- Blood chemistry: measures waste products such as creatinine and BUN, plus SDMA, which can rise earlier in the disease
- Urinalysis: checks how well your pet concentrates urine and looks for infection
- Urine protein testing: looks for protein loss, which can affect treatment choices
- Blood pressure: high blood pressure is common with kidney disease and can damage the eyes, heart and brain
- Imaging: your vet may recommend X-rays or ultrasound to look at kidney size and shape or check for stones
Caring for a Pet With Kidney Disease at Home
Chronic kidney disease cannot be reversed, but many pets live comfortably for months or years with good home care. Always keep fresh water available, since pets with kidney disease lose more water in their urine. A prescription kidney diet is one of the most helpful steps, and your vet can suggest ways to make it appealing if your pet is picky.
Some pets benefit from fluids given under the skin at home, and your vet can tell you whether this is a good option. Keep up with recheck visits so your vet can adjust treatment as needed. Call us or come in right away if your pet stops eating, vomits repeatedly, seems very weak or stops urinating.
