Cat Kidney Disease Symptoms: Early Signs Every Owner Should Know
The earliest signs of kidney disease in cats include increased thirst and urination, weight loss, poor coat condition, and subtle changes like hiding or decreased appetite. These symptoms often appear gradually, making them easy to mistake for normal aging.
Early Warning Signs of Kidney Disease in Cats
Kidney disease in cats often develops slowly, and the earliest signs can be easy to miss. Watch for these changes in your cat's behavior and health:
- Increased thirst and urination – Your cat may drink more water and visit the litter box more often, producing larger clumps of urine.
- Weight loss – Even if your cat still eats, you might notice a gradual decrease in body condition, especially along the spine and hips.
- Poor coat condition – The fur may look greasy, unkempt, or matted, as your cat may groom less due to feeling unwell.
- Decreased appetite – Your cat might show less interest in food or eat smaller portions than usual.
- Lethargy or hiding – A cat with early kidney disease may sleep more, become less playful, or hide in quiet spots.
- Vomiting or bad breath – Some cats develop a foul odor to their breath (like ammonia) or vomit occasionally as waste products build up.
If you notice any combination of these signs, especially in a cat over 7 years old, it's time to talk to a veterinarian. Catching it early can make a significant difference in managing the condition. For more details on what to watch for, see our complete guide on [[cat-kidney-disease-symptoms|cat kidney disease symptoms]].
Is It Normal Aging or Kidney Disease? How to Tell the Difference
It's common to wonder if changes in your older cat are just part of getting older or something more serious. This table can help you decide when to be concerned:
| Sign | Normal Aging | Possible Kidney Disease |
|---|---|---|
| Thirst | Stable water intake; slight increase in warm weather | Noticeably increased thirst, drinking from unusual places (e.g., faucets) |
| Urination | Litter box habits consistent; no increase in frequency | More frequent trips to the box, larger urine clumps, or accidents outside the box |
| Weight | Gradual, slight weight loss over years | More rapid or significant weight loss over weeks to months |
| Coat | May be slightly less shiny but still well-groomed | Dull, greasy, or matted; reduced grooming |
| Appetite | May eat less but still interested in food | Decreased appetite or picky eating; may lose interest in favorite treats |
| Energy | Sleeps more but still engages in play | Lethargic, hides, less interactive |
If your cat shows two or more of the signs in the right column, it's wise to schedule a checkup. Our team at Cats Only Clinic in Rocklin can help you distinguish between normal aging and early disease.
What to Do If You Notice Signs of Kidney Disease in Your Cat
If you've spotted potential early signs, take these steps right away:
- Monitor and document – Track how much your cat drinks, how often they urinate, and any other changes in behavior or appetite. Note the date when you first noticed symptoms.
- Check for other symptoms – Look for vomiting, bad breath, or changes in coat condition. This helps your vet get a full picture.
- Call us for an appointment – Contact Cats Only Clinic at (916) 435-9300. We're open Monday through Saturday, and we recommend booking an appointment, though we can accommodate walk-ins.
- Bring a urine sample if possible – Collect a fresh sample using a non-absorbent litter or a clean container. This can speed up diagnosis.
- Prepare for the visit – Bring any records of your cat's health history and a list of questions. Our team will perform a thorough exam and recommend diagnostics.
If your cat is showing severe signs like not eating for more than 24 hours, vomiting repeatedly, or acting extremely lethargic, seek immediate veterinary care. For more on when to act, read our guide on [[when-take-cat-to-vet|when to take your cat to the vet]].
How Vets Diagnose Early Stage Kidney Disease in Cats
At Cats Only Clinic, we use simple, reliable tests to confirm or rule out kidney disease. The main diagnostics include bloodwork and urinalysis. Here's what to expect:
| Test | What It Checks | What It Reveals |
|---|---|---|
| Blood chemistry panel | Kidney values (BUN, creatinine, SDMA) | Elevated levels indicate reduced kidney function |
| Complete blood count | Red and white blood cells, platelets | Anemia or infection that may accompany kidney disease |
| Urinalysis | Urine concentration, protein, cells | Dilute urine or protein loss suggests kidney damage |
| Blood pressure measurement | Blood pressure | High blood pressure is common with kidney disease |
These tests help us stage the disease using the IRIS system, guiding treatment and monitoring. Most results are available within the same day. For more about costs, see the next section.

How often should I test my older cat for kidney disease?
For cats over 7 years old, annual bloodwork and urinalysis are recommended. If your cat has risk factors like dental disease or high blood pressure, more frequent testing may be advised.
What is the IRIS stage for early kidney disease?
Early kidney disease is typically classified as IRIS Stage 1 or 2, based on creatinine and SDMA levels. Stage 1 often has no visible symptoms, while Stage 2 may show mild signs like increased thirst.
