Katkor is a cat litter pellet that does not absorb moisture and is therefore very suitable for collecting urine samples. With these pellets, you can collect urine yourself for urinalysis for the different types of bladder stones, specific gravity, blood, protein etc by your vet. On the other hand, if the urine needs to be obtained for bacteriological testing, it is recommended to have this done at your vet's office. Katkor can also be used when collecting stool for examination for worm eggs and digestive indicators, among others.
