Urine Sampling in your Cat

How to Collect a Urine Sample from your Cat;

If you have an idea of when you cat usually uses the litter tray this will help you in collecting a sample. Most cats have a routine, morning, evening or after a meal.

Empty Litter Tray
Empty your cat’s litter tray. Clean and dry it well, then place the litter box down in it’s normal position, without any litter in it. If you cat then urinates in the empty box, you can then just pour the urine from the box into a clean container with a lid.

Some cats may refuse to use an empty tray so you can try non absorbing litter instead.

Non absorbing Litter(Katkor)
Non absorbing litter can be placed into the clean tray. Most cats will then use the tray. Instead of being soaked into the litter, the urine will pool in the bottom of the tray. The urine can then be collected using a syringe or pipette and placed into a clean container. Non absorbing litter called Katkor can be bought from Beech House.

Free Catch Mid Stream
If your cat refuses both of the above you could try to catch him in the tray or outdoors and when he squats to urinate, place a container underneath him to try to collect urine mid stream. Some cats may be deterred from urinating by this and stop when you approach. But, if you catch them with a very full bladder, such as first thing in the morning, you may be able to catch enough for analysis. We only need a small amount.


It can help to isolate your cat without access to the litter tray for a short period. This will increase your chances of getting a sample when he is then given access to the tray again. Do not deny access to a tray for too long. A few hours should suffice. But do remember to provide water and or moist food to ensure a large bladder.

If you have multiple cats in your household you will need to isolate your cat to ensure the urine you collect is from the correct pet.

Urine collection does take time and patience and some luck!

Please use clean and dry containers for collection and storage of urine samples. Containers which previously contained sugar, such as jam jars, may cause inaccuracy in the analysis if not properly cleaned prior to use.

Once you have collected the sample, the sooner you can bring it to us the better. Changes can occur over time - bacteria can multiply and crystals can dissolve. If you can't get the sample to us straight away, keep it in a sealed container in the fridge.

Please provide sample labelled with your pets name, your name and the date collected.

BHVC would advise you to wear gloves or wash your hands after handling urine and please be aware that pregnant women should not have contact with cat urine.

If all else fails, contact Beech House as there are other ways to collect a urine sample but would require you to bring your pet in to us.
