Collecting your cat's urine

at home, with Kit4Cat

Has your vet asked for a urine sample? Kit4Cat is a special litter that does not absorb urine, making home collection simple, even for fussy cats. Here is how to do it, and how to keep the sample usable until it reaches the clinic.

Why

Why test your cat's urine

A simple urine sample tells your vet a lot about your cat's health. The analysis helps spot:

Urinary infections

Cystitis, bladder infection.

Metabolic problems

Diabetes, kidney disease, and other imbalances.

Clues under the microscope

Blood, crystals, or bacteria.

What is Kit4Cat?

A hydrophobic litter: it does not absorb urine, which stays in droplets on the surface. That lets you collect a clean, free-catch sample at home, often more easily than with other methods.

Get ready

What you need

The kit has the essentials. Get the rest ready before you start.

  • The Kit4Cat kit: the hydrophobic litter, a pipette, and a collection vial.
  • An empty, clean litter box, without your usual litter.
  • A sealed bag or container for transport (if the clinic did not provide one).
  • Gloves (optional), for extra hygiene.

Collection

Collection in 6 steps

The method is simple. Go at your cat's pace, without rushing it.

1

Pour the litter

Empty and clean the box, then pour all the Kit4Cat litter in a thin, even layer.

2

Let your cat use it

Let your cat use this 'special' box at its own pace. Some are surprised at first: give it a little time to get used to it.

3

Collect the urine

Once your cat has urinated, the urine beads on the surface (the litter does not absorb it). With the pipette, gently draw up the urine while avoiding the granules.

Aim for the clear droplets on the surface, without dipping the pipette into the litter.
4

Fill the vial

Transfer the urine into the supplied vial, to about three-quarters full. That is enough for most tests.

5

Store the vial

Close the vial tightly. If you cannot bring it right away, keep it in the fridge, never the freezer.

6

Bring it to the clinic

Bring the sample as soon as possible: ideally within 1 to 2 hours, at the latest within 12 to 24 hours.

Freshness

Freshness and timing: what matters

A fresh sample gives reliable results. Urine changes over time (pH, crystals, bacteria), which can skew the analysis. A small fresh sample beats a large stale one.

Ideal: 1 to 2 hours

Bring the sample as soon as possible after collection.

Acceptable: 12 to 24 hours

Refrigerated, and for some tests only. Always tell the team the collection time.

Never freeze it

Never freeze the urine: freezing damages the sample and skews the results. The fridge is enough.

Label the vial

Write your cat's name, the date, and the time of collection on the vial. It helps the clinic interpret the result.

Troubleshooting

If things don't go as planned

A few common situations, and what to do.

Your cat refuses the special litter

Leave the box for a few hours in a quiet spot. If it stays reluctant, talk to the clinic: another method (such as cystocentesis) is possible.

Very little urine?

A few millilitres are often enough (about 2 to 3 pipettes). If unsure, ask the team whether the amount is enough.

Several cats at home?

Isolate the right cat with the special box, so you are sure the sample is its own.

FAQ

Your questions, our answers

The most common questions about collecting with Kit4Cat.

Is it a problem if a few litter granules end up in the urine?
It is not ideal, but a tiny bit of litter will not make the sample unusable. Remove as much as you can with the pipette.
How long can I leave the Kit4Cat litter in the box?
Up to 24 hours if your cat has not urinated. If it has not used the box within that time, you may need to start over with fresh litter for a good sample.
My cat is very particular. Can I add a little of its usual litter on top?
No. The whole point of Kit4Cat is to stay hydrophobic. Adding another litter makes it lose that property. Better to follow the kit's instructions.
How long does the sample stay valid?
Ideally 1 to 2 hours after collection. Beyond that, changes (pH, crystals) can appear. Up to 12 to 24 hours refrigerated is still acceptable for some tests: always tell your vet the timing.
My cat urinated very little. Is that enough?
Often yes: a few millilitres can be enough. Ask the veterinary team whether it is enough or whether it is better to try again.

A fresh sample, and you are set

Pour the litter, let your cat do its thing, draw it up with the pipette, transfer, keep it cool, and bring it in quickly. If you run into trouble or your cat snubs the litter, call us: we have other ways to get a good sample.
