- 💨 99% DUST-FREE MICRO CRYSTALS: The silica-gel granules are advertised as 99% dust-free and unscented, reducing added fragrance while supporting everyday litter-box maintenance.
- 🪶 60% LIGHTER FORMULA: Advertised as 60% lighter than traditional litter, making the 5 lb bag easier to carry, pour and replace than many heavier clay products.
- 🗓️ UP TO 30 DAYS PER CAT: One 5 lb bag is designed to provide up to one month of odour control for one cat. Actual duration varies with box size, use, humidity and maintenance.
Ultra by Cat’s Pride Health Monitor Crystal Cat Litter
Ultra by Cat’s Pride Health Monitor combines unscented micro-crystal litter with colour-changing pH indicator technology. After contact with fresh urine, treated granules display different colours associated with the urine’s approximate pH range.
This visual information may help an owner notice a persistent change and decide when to speak with a veterinarian. It does not identify the cause of that change and should never replace a physical examination, urinalysis or other veterinary testing.
Understanding the Colour-Changing pH Indicator
The product uses selected indicator granules that respond to urine pH. According to the manufacturer’s colour key:
- Blue to dark green: Higher or more alkaline pH
- Olive green to yellow: Manufacturer’s standard display range
- Deep yellow to orange: Lower or more acidic pH
- Red granules: Possible blood or another source of red discolouration; contact a veterinarian promptly
Compare the granules only with the current colour guide printed on the received package. Lighting, moisture, cleaning products and the age of the litter can affect how colours appear.
What a Colour Change Means
A colour change is an observation, not a diagnosis. Abnormal urine pH may occur for several reasons, including diet, hydration, medication, sample contamination and different urinary conditions.
The litter cannot determine whether a cat has:
- A urinary tract infection
- Bladder or urinary stones
- Kidney disease
- Acidosis or alkalosis
- Blood in the urine
- Another urinary or metabolic condition
Only a veterinarian can interpret clinical signs and perform appropriate diagnostic testing.
When to Contact a Veterinarian
Contact a veterinarian when an unusual colour appears repeatedly in fresh urine spots or when the cat’s behaviour changes.
Seek urgent veterinary care if a cat:
- Strains repeatedly in the litter box
- Produces little or no urine
- Cries or shows pain while urinating
- Makes frequent unsuccessful trips to the box
- Has visible blood in the urine
- Licks the urinary area excessively
- Urinates outside the litter box unexpectedly
- Becomes weak, restless, withdrawn or stops eating
- Develops a firm or painful abdomen
Urinary Blockage Warning
Inability to urinate can be a life-threatening emergency, particularly in male cats. Do not wait for the litter colour to change and do not attempt home treatment if a cat is straining without producing urine.
More Reliable At-Home Monitoring
Observe a fresh urine area under consistent lighting and compare it with the package guide. A single colour result should not be used to make treatment decisions.
If several cats share one litter box, the result cannot reliably identify which cat produced the urine. Separate, clean boxes may be needed for individual observation, provided isolation does not cause unnecessary stress.
Record the date, colour, urinary frequency and any behavioural changes. Photographs taken under similar lighting may help a veterinarian understand the pattern, but they are not a substitute for a urine sample or examination.
Unscented Micro-Crystal Litter
The litter consists of silica-gel micro crystals that absorb moisture and help manage odour without added fragrance. The manufacturer advertises continuous odour control for up to 30 days for one cat.
Performance varies according to:
- Number of cats
- Frequency of litter-box use
- Box dimensions
- Depth of litter
- Daily maintenance
- Indoor humidity
- Urine volume
- Solid-waste removal
- Individual cat habits
Replace the litter sooner if it becomes saturated, develops a persistent odour or no longer provides a clean surface.
99% Dust-Free Formula
The product is advertised as 99% dust-free, not completely dust-free. Pour it slowly and close to the bottom of the litter box to reduce airborne particles.
If the cat or household member has respiratory sensitivity, stop using the product if coughing, wheezing, eye irritation or breathing discomfort occurs and seek appropriate professional advice.
Lightweight 5 lb Bag
Cat’s Pride describes the formula as 60% lighter than traditional litter. The lighter bag may be easier to carry and pour, particularly for owners who find large clay-litter containers difficult to handle.
The comparison basis is not fully detailed on the Amazon page, so the statement should remain qualified as a manufacturer-advertised comparison rather than an absolute performance claim.
How to Use the Crystal Litter
Setting Up the Litter Box
Empty and clean the litter box before changing litter types. Rinse away cleaning-product residue and allow the box to dry completely.
Add the amount of litter specified on the current bag. The Amazon source does not provide a complete fill-depth instruction, so do not estimate a required depth from third-party information.
Daily Maintenance
- Remove solid waste promptly.
- Observe fresh urine areas for colour changes.
- Follow the bag instructions for mixing or redistributing crystals.
- Keep the surrounding floor clean and dry.
- Add or replace litter only as directed.
- Wash hands thoroughly after handling waste.
- Maintain enough boxes for the number of cats in the home.
A commonly used guideline is one litter box per cat plus one additional box, but individual households and veterinary recommendations may differ.
Transitioning from Another Litter
Cats can be sensitive to changes in litter texture. Follow the manufacturer’s transition guidance and monitor whether the cat continues using the box normally.
Do not force a sudden change if it causes litter-box avoidance. Contact a veterinarian if inappropriate urination begins, since behavioural and medical causes may both require evaluation.
One Bag, One Cat, Up to One Month
The manufacturer markets one 5 lb bag as lasting up to 30 days for one cat. This is an estimated maximum, not a guaranteed replacement schedule.
Multiple cats, high urine output, smaller boxes and humid environments may shorten usable life. Follow the condition of the litter rather than relying only on the calendar.

Safety and Disposal
Safe Handling
Crystal litter is not food. Prevent cats, children and other animals from intentionally eating the granules. Contact a veterinarian or poison-information service if a significant amount is swallowed.
Although the formula is advertised as low dust, avoid deliberately inhaling particles. Pour slowly in a ventilated area and wash hands after litter-box maintenance.
Important Precautions
- Use the product only as directed on the current package.
- Keep the unused litter dry and securely stored.
- Do not mix it with household chemicals or cleaning agents.
- Never use bleach in a litter box containing urine.
- Do not rely on colour alone when a cat appears unwell.
- Do not administer medication based on a colour result.
- Do not flush litter or cat waste unless the package and local wastewater authority explicitly permit it.
- Dispose of used litter according to local waste rules.
- Clean the box with products suitable for cats and rinse thoroughly.
- Keep food and water bowls away from the litter area.
Pregnancy and Reduced Immunity
Cat waste can carry infectious organisms. Pregnant people and individuals with weakened immune systems should avoid litter-box cleaning when possible or follow medical guidance regarding gloves, hygiene and daily waste removal.
Not a Veterinary Diagnostic Test
This product is a household observation aid. It does not replace veterinary urinalysis, urine culture, imaging, blood testing or physical examination.
A standard-looking colour cannot rule out disease, and an unusual colour does not confirm a specific diagnosis. Behavioural changes and difficulty urinating require veterinary attention regardless of the displayed colour.
