HEAlth indicator®


Health Indicator can be used with
ALL*   sorts cat litter. 

 The additive reacts with the urine of the cat and will result 
into a color change of the litter on the spot where the cat urinated.  

After completing the test stir the HEALTH INDICATOR® into the regular litter 
where it will help eliminate odors.

No. Only your veterinarian has the knowledge and experience to diagnose your cat’s health. Health Indicator is a tool to help you monitor your cat’s health. When your cat urinates in the litter box the crystals will absorb all the urine. If certain abnormalities in pH are present in the urine the crystals changes to certain colors.

Inside each bag is a Health Indicator card with a color bar along one side. Use this card to compare colors at the urination spot. If the card was missing, you can print another one off our website. If blue, green, red, or orange are present then your cat‘s urine is showing signs of a potential problem. We recommend that you contact the cat’s veterinarian for advice.

  • Begin with a clean litter box.
  • Using disposable gloves scrub the box with a mild detergent and thoroughly rinse and dry. Avoid using ammonia or other strong cleaners as the residual smell can deter litter box use.
  • Fill the litter box with the cat’s normal litter.
  • Spread the Health Indicator evenly across the top of the litter.
  • Watch your cat for litter box visits.
  • Shortly after the cat leaves the litter box check the urination spot for color changes.
  • Compare the color at the urination spot with the colors on the card enclosed in each Health Indicator bag.
  • If the color compares with a color that indicates a high pH (blue or green) or a low pH (red or orange) then contact your cat’s veterinarian for advice.
  • If the color indicates normal pH (light gold to light olive) stir the Health Indicator into the regular litter where it can help with odor control for up to a month.

No, it will not give an accurate reading. Health Indicator is designed as a single use product – once per month you check your cat for proper urine pH. When the cat urinates on the Health Indicator the color is apparent for an hour or so and then fades. To get the most accurate reading it is important to check the urine spot within 5 minutes of the cat leaving the litter box.

It depends on your cat’s urination pattern. If your cat has a “habitual urination spot” in the litter box, a portion of the bag can be poured in the spot and checked and then stirred into the litter. Then the spot can be refreshed with fresh Health Indicator later in the month. We have found that repeated test on the same product can result in less accurate test as the pH indicators will be diluted by the previous urinations.

An alternative method should be used if the cat being monitored typically digs a depression prior to urinating. Empty the litter box and clean according to litter box manufacturer recommendations. Spread the Health Indicator evenly across the bottom of the litter box. After checking the color at the urination spot, refill the litter box with the normal litter. The Health Indicator will help control odors over the month if it is stirred into the regular litter.

We recommend using a double layer litter box that allows you to collect the urine in a pan. Then you can pour Health Indicator into the urine and be able to check the color changes.

The normal colour, when urine is added to the litter, is either light- to dark yellow.
Should any other colour become visible, immediately contact your vet (abnormally discoloured litter should be removed with a plastic cup, or spoon.

MAYBE. Urine pH is affected by many factors-some health related and others are related to diet. (See Question: What causes pH fluctuations in urine?) If the Health Indicator changes to one of the colors indicating the cat‘s urine is registering abnormal (blue, green, red, or orange) this MAY indicate the cat is suffering with Feline Lower Urinary Track Disease. FLUTD can only be diagnosed by a veterinarian so it is recommended that if one of these colors is indicated you should consult with your cat’s veterinarian.

  • Potential Causes of High pH (Alkaline)
  • Inferior Food or eating only large meals a few times per day
  • Too much magnesium and phosphorus in diet
  • Not enough water being consumed (urine is too concentrated)
  • Bladder Infections
  • Bladder Stones/Crystals with Struvite (magnesium ammonium phosphate)
  • Urethral plugs
  • Some Kidney Diseases
  • Dysuria (pain during urination)Potential Causes of Low pH (Acidic)
  • Too many acidifiers in food
  • Bladder stones – Calcium oxalate stones usually need to be surgically removed
  • Urethral plugs
  • Dysuria (pain during urination)
  • Blood in Urine
  • Urine is too concentrated – not enough water consumption

Any time there are concerns for your cat’s health, it is important to contact the cat’s veterinarian for advice. Health Indicator is not able to diagnose diseases that may affect your cat. It is able to indicate the pH of the urine which can be an indicator of health problems or potential for health problems such as poor quality foods.

If cat appears to be in excellent health, you may choose to wait one day and recheck for abnormal colors over the next 24 hours. It is possible that something your cat has eaten has temporarily changed the pH of the urine. If the abnormal color persists we recommend the cat’s veterinarian be contacted for advice.

  • Straining to urinate
  • Frequent and/or prolonged attempts to urinate
  • Crying out while straining to urinate
  • Excessive licking of the genital area
  • Urinating outside the litter box
  • An increased amount of urination
  • Minimal or no urination
  • Thick gelatinous urine
  • Extreme nervousness
  • Abnormal urine pH indicated by  Health Indicator
  • Blood in the urine

**Note that cats with a urethral obstruction will also show these signs but will pass little or no urine and become increasingly distressed.
A urethral obstruction is an emergency and requires immediate veterinary treatment.
Death can occur if a urethral obstruction is not treated immediately.**

Unless it is very obvious which cat is sick then you will need to determine which cat has the problem. Isolate each cat with its own litter box with  Health Indicator . Watch each cat and when they visit the litter box check the urination spots with the pH color card that comes in each bag to determine which cat is having the potential problem.

Keep the unopened bag in a dry location away from direct sunlight.

Although HEALTH INDICATOR® works with almost all types of cat litter it can occur the cat litter you use has an effect on the test result.
We have a very simple but effective compatibility test so you can try out the correct operation of HEALTH INDICATOR® in advance.

Important Notices:

Health Indicator cannot detect every urinary abnormality, only your cat’s veterinarian can undertake such a diagnosis. Health Indicator is NOT for “at home diagnosis” and should NEVER be used as a substitute for veterinary care! If you feel your cat is having health or urinary problems contact your veterinarian even if the Health Indicator has not shown colors in the low or high pH ranges.

* Some edited Cat Litters give different results.
With our simple compatibility test you can test the correct operation of HEALTH INDICATOR® in advance.
If advice is desired send us an email.

Cat faeces can transmit a disease called toxoplasmosis.  Pregnant, nursing, or persons with a suppressed immune system should use caution & thoroughly wash hands after handling soiled litter.
