Katkor is the reliable way to collect urine

Katkor is a cat litter that does not absorb moisture and is therefore very suitable for collecting urine samples.

Your veterinarian can now easily distinguish between the different types of crystals (calcium oxalate, urate and struvite crystals) if bladder stones are suspected. The choice of a specific anti-truvite diet or a diet for oxalate or urate urolithiasis becomes easier. Your veterinarian can also determine more accurately when to switch from a bladder grit dissolving to a bladder grit preventive diet. Katkor is also ideal for taking urine samples for protein, glucose, ketone, blood and specific gravity testing.

In addition, Katkor can also be used for the collection of faeces for research on worm eggs and digestion indicators. If, on the other hand, the urine has to be obtained for bacteriological examination, it is recommended to collect it aseptically by means of a bladder puncture.

I got KATKOR from the veterinarian and want more information on how to use KATKOR.

How to use Katkor

1. Clean the litter box well. Then rinse it well with clean, lukewarm water so that no detergent or bleach residue remains. Then dry the litter box using kitchen or toilet paper.

2. Sprinkle Katkor in the center of the container. Return the tray to the place the cat is used to.

3. If the cat produces stool rather than urine, the stool should be removed as soon as possible to avoid any contamination of the urine to be collected.

4. The urine should be collected as soon as possible after urination. Squeeze the balloon of the supplied pipette and tilt the container to a point. Insert the end of the pipette into the deepest point of the container, then release the balloon. The urine will now be sucked up.

5.The urine thus absorbed should be placed in the supplied collection tube and delivered to the veterinarian as soon as possible. This is important because the urine composition and crystal shape can change if the urine is stored for a long time.

6. A cat may not be satisfied with the amount of pellets. In that case you can use two containers of Katkor. In most cases, only 1-2 ml of urine is required for the desired exams. With a bowl of Katkor there is a refund of 7 ml of urine per 10 ml of urine discharged by the cat. Cats produce an average of 35 – 80 ml (on dry food) to 80 – 120 ml urine per day, so collecting enough urine will not be a problem in most cases. Only with a bladder infection the cat produces only a few drops at a time. In that case, enough urine will probably still have been collected after some time (1 – 2 hours). The urine that has already been collected should not be kept in the refrigerator in the meantime, as crystals may form.

7. If the cat really does not want to sit on the litter box with Katkor, ordinary cat litter can be placed in a corner of the box. This way the familiar scent remains. It is very important to ensure that the urine sample does not become contaminated with the normal granules. However, since there is a risk of contamination, this method should only be used in extreme cases.

Accountability Katkor

Katkor is a brand name of a copolymer product and has two safety certificates: from the BGA (Bundesgesundheidsamtes) and the FDA (Food and Drugs Administration). These certificates have been obtained in connection with the use for food preparation.

Proven, katkor does not affect urine test results. In a study by the AZU it has been shown that Katkor has no influence on the pH values ​​(acidity) to be measured, the amount of protein and the numbers of white and red blood cells in (human) urine (Dec 1996, FL projects).

The 4 Ways To Obtain Urine From Your Cat

There are four methods of obtaining urine:

  • spontaneously discharged urine,
  • manual emptying of the bladder,
  • catheterization,
  • cystocentesis

Spontaneously discharged urine is the cat owner’s only option. Manual emptying of the bladder, catheterization and cystocentesis are options that can be used by the veterinarian.

Spontaneously discharged urine:
Clean the litter box well. Sprinkle the non-absorbent granules, catcorn into the tray. If the cat has visited the tray, tilt the tray. The urine will now flow to the lowest point. Insert the tip of the pipette through the beads and then aspirate the urine.

Manually pushing the bladder empty:
The vet will apply continuous – no pumping or squeezing – pressure to the bladder for several tens of seconds until the cat starts to urinate. Within a minute it is clear whether this method is successful.

A catheter is introduced into the bladder through the urethra. Often the cat needs to be sedated (a light anesthetic).
The puncture site is shaved and disinfected. With one hand the bladder is immobilized and with the other hand a sterile needle is inserted into the bladder through the abdominal wall. Now the urine can be sucked up.


Spontaneous urination using katkor is a cat-friendly method for obtaining urine. For determining the creatinine / cortisol ratio in cushing, the cat’s spontaneous urination in its familiar environment is the appropriate method of obtaining urine. If the vet needs urine during the consultation hour, it is best to first try to get the cat to urinate by applying light pressure on the bladder. If this does not work – for example due to resistance from the cat – or if you need sterile urine, then puncturing is the appropriate method. In the case of an overfilled bladder due to obstruction of the urethra, catheterisation will have to take place to make the urethra fit.
