Cat Urine Color Chart: Healthy vs. Unhealthy Colors

As a cat owner, learning to identify changes in your cat’s urine color can help you spot dehydration, kidney issues, infection, and even emergencies before they progress. Cats tend to mask discomfort and illness, so clues in the litter box are sometimes the first—and only—signs that something is wrong. This guide breaks down cat urine color meanings, from healthy hues to warning and emergency signals, empowering you to protect your cat’s health.

Why Monitoring Cat Urine Matters

Cats’ survival instincts lead them to hide pain or illness. Subtle litter box clues—such as urine color, odor, or frequency changes—can indicate everything from mild dehydration to life-threatening blockages. Early intervention makes an enormous difference, so knowing what’s normal and what’s a red flag is essential for every responsible cat guardian.

Normal Cat Urine Colors

The baseline of healthy cat urine is a clear, pale yellow. This shade, often called “straw-colored” or “golden,” suggests your cat is well-hydrated and all major urinary system functions are normal.

Normal cat urine characteristics:

  • Color: Clear, pale yellow, straw, or golden.
  • Odor: Slightly pungent or acidic, but not overpowering.
  • Clarity: Easy to see through; no cloudiness or floating debris.
  • Consistency: Steady and moderate in volume, assuming normal hydration.

Adult, healthy cats—regardless of sex—will usually produce pale yellow urine.
Intact males may sometimes have more concentrated urine, which can slightly darken the shade but should remain within normal parameters.

Abnormal Cat Urine Colors and What They Mean

Certain changes in urine color can be the first—and sometimes only—signal of an underlying health issue. Below is a breakdown of colors that warrant attention:

  • Dark Yellow: Suggests dehydration. Can occur during heat, illness, or poor water consumption.
  • Cloudy/Hazy: May indicate urinary tract infection (UTI), inflammation, or the presence of crystals or debris.
  • Brown: Possible blood presence, muscle breakdown, or severe infection. May signal chronic or severe kidney/urinary conditions.
  • Red/Pink/Red-Brown: Blood in urine—emergency indication of trauma, stones, infection or serious illness.
  • Orange/Yellow-Orange: May be dehydration or a liver/biliary issue; sometimes linked to medication or dietary factors.
  • Completely Clear: Could suggest excessive drinking (possibly due to diabetes, kidney disease) or reduced kidney function.

Ignore sudden color changes in cat pee at your cat’s peril—address them as potential medical emergencies for optimal safety.

Cat Urine Color Chart

The following chart can help you quickly interpret what you see in the litter box, and decide when to act:

ColorPossible Health MeaningAction Steps
Clear, pale amber, light yellowGenerally healthy; may mask kidney problems if frequent, excessive or changed behavior.Monitor for other symptoms; vet check if paired with unusual frequency or litterbox accidents.
Dark yellowDehydration or high urine concentration.Encourage water intake; vet if persists despite hydration, or other signs arise.
CloudyUTI, crystals, or inflammation. May be visible as bits or particulates in urine.Book a veterinary appointment promptly; infection can worsen fast.
BrownBlood in urine, severe infection, potential kidney disease or muscle breakdown.Urgent vet diagnostic workup required.
Red, pink, reddishFresh blood; trauma, stones, cancer, UTI, or severe inflammation.Immediate emergency vet visit—do not wait.
Orange/yellow-orangeDehydration or possible liver/biliary disease.Vet consult recommended, especially if paired with lethargy or jaundice.
Completely clearPossible kidney function decline or excessive water intake (diabetes, Cushing’s).Vet checkup for underlying disease if paired with behavioral or frequency changes.

When to Call the Vet

Knowing when urine color changes signal an emergency versus something less urgent can save your cat’s life. Contact your veterinarian in any of these situations:

  • Your cat’s urine is cloudy, brown, red, pink, or contains visible blood
  • Unusual urine color persists for more than 24 hours
  • Unexplained litter box accidents, straining, or urgency accompany the color change
  • Your cat is lethargic, losing appetite, vomiting, or hiding
  • Frequent urination, or obvious pain during urination, is noted

Bloody or dark urine is always an emergency.
Never delay care if you see red, pink, or brown urine, as some causes can be rapidly fatal without prompt intervention.

Does Litter Type Affect What You See?

Certain litters (such as dyed, scented, or colored variations) may obscure or affect how urine color appears. Familiarize yourself with how your litter looks when wet by healthy urine, so you can quickly notice any deviations.

Transparent, pale urine can fade into light-colored litter, while colored, crystal, or clumping litters can mask or exaggerate darker shades. Assess changes up close, and consider switching to a plain, unscented, or low-dust option if visibility is a concern.

DIY Urinalysis & PrettyLitter Explanations

Cat owners often wonder if home solutions like PrettyLitter or DIY visual checks provide meaningful health diagnostics.

PrettyLitter is a commercial crystal litter that reacts to urine pH change—its colors range from yellow/green for normal, blue for high pH, orange for low pH, and red for blood in urine. While it can signal potential problems, it’s not a definitive diagnostic tool. The color reflects acidity, one of several health markers. Positive experiences (like early warning for kidney or bladder disease) exist, but missed signals are common—owners must use it as a supplement, not a substitute, for veterinary care.

PrettyLitter ColorWhat It MeansPossible Sources
Olive Green/YellowNormal pH (healthy urine)No associated disease states
BlueHigh pHPossible struvite crystals, bacterial UTI
OrangeLow pHCalcium oxalate crystals, metabolic/kidney acidosis, some UTIs
RedBlood detectedBladder stones, cancer, severe infection, acute inflammation

DIY Tests: Visual checks using a clean, white, unscented clumping litter and good lighting can allow for a crude assessment. However, urine tests at a vet clinic provide reliable information about infections, crystals, kidney and liver function, and underlying disease. Use home checks to catch problems early, but always follow up with a professional for any concerning change.

Frequently Asked Questions (FAQ)

What does healthy cat urine look like?

Healthy cat urine is clear, pale yellow, and see-through. It should not be cloudy, dark, or contain visible blood. Odor is usually mild but distinctive.

Is male cat pee different in color from female cat pee?

No. Both male and female cats produce pale yellow urine when healthy. Unneutered males may have more concentrated urine, but color should remain within normal range.

How much water should my cat drink to stay hydrated?

On average, cats need around 4 ounces of water per 5 pounds of body weight daily. Wet food, water fountains, and several fresh bowls can support hydration.

Does cloudy or murky urine mean my cat has a UTI?

Cloudy urine may signal UTI, crystals, or other types of inflammation. Prompt vet attention is advised.

Are home urine test litters like PrettyLitter reliable?

They can alert you to changes in pH or presence of blood, but they’re not a replacement for professional urine analysis. Always confirm results with a vet if abnormalities occur.

What if urine looks normal, but my cat is acting sick?

Behavioral changes (such as straining, accidents, reluctance to urinate) may signal underlying disease even if the urine appears normal. Always pay attention to both urine appearance and litter box habits.

What other health signs should I watch for, along with urine changes?

  • Straining or pain while urinating
  • Frequent, small trips to the litter box
  • Crying or agitation during urination
  • Unexplained litter box avoidance
  • Lethargy, weight loss, vomiting, appetite change

When in doubt, consult a veterinarian—early action keeps your feline healthy and happy.
