How to preserve cat urine? - briefly

To preserve cat urine, it should be stored in a sealed container at a temperature between 4°C (39°F) and -20°C (-4°F). Adding a small amount of sodium azide can help prevent bacterial growth during storage.

How to preserve cat urine? - in detail

Preserving cat urine can be essential for various reasons, including medical diagnostics or behavioral studies. Here is a detailed guide on how to properly collect and store feline urine:

  1. Collection Method:

    • Cleanliness: Ensure that the collection container is clean to avoid contamination. A sterile container is ideal but not always necessary unless required for medical purposes.
    • Container Type: Use a screw-top plastic or glass container with a secure lid. Avoid containers made of materials that can absorb odors, such as cardboard or paper.
    • Collection Technique: Place the collection container in the litter box or another area where the cat is likely to urinate. Some cats may require a more targeted approach, like using a syringe or catheter if collecting from an animal under sedation or during a veterinary procedure.
  2. Immediate Storage:

    • Once the urine has been collected, secure the lid tightly on the container to prevent leakage and minimize exposure to air.
    • Label the container with the date and time of collection, as well as any relevant information about the cat (e.g., age, sex, health status).
  3. Refrigeration:

    • Store the urine sample in a refrigerator at a temperature between 2°C to 8°C (36°F to 46°F) as soon as possible after collection. Refrigeration helps slow down bacterial growth and preserves the integrity of the sample.
    • Ensure that the container is placed away from strong-smelling foods or substances to prevent odor absorption.
  4. Long-Term Storage:

    • For long-term storage, consider freezing the urine sample. Freeze it at a temperature of -20°C (-4°F) or lower. This method is particularly useful if the sample needs to be stored for more than a few days.
    • Use appropriate freezer-safe containers and ensure they are properly labeled with all relevant information, including the date of collection and storage instructions.
  5. Transportation:

    • If transporting the urine sample to a laboratory or veterinary clinic, pack it in an insulated container with ice packs to maintain its temperature during transit.
    • Ensure that the packaging is secure and leak-proof to prevent any spillage or contamination.
  6. Safety Precautions:

    • Always handle cat urine with care, using gloves and other protective gear if necessary. Cat urine can contain bacteria and other pathogens that may pose a health risk.
    • Dispose of used collection containers properly to avoid environmental contamination.

By following these detailed steps, you can effectively preserve cat urine for various purposes, ensuring the integrity and reliability of the sample throughout its storage and use.
