The Science Behind Cat Period Stains

A cat's period, also known as estrus, occurs when a female cat is in heat and ready to mate. During this time, the cat's body releases a blood-like substance called estrus blood, which is expelled from the vagina. Estrus blood can stain clothing because it contains pigments called hemoglobin and myoglobin, which are responsible for giving the blood its red color. The pigments can bond with the fabric fibers of clothing, making it difficult to remove the stain.

  • Cold water
  • Dish soap
  • Hydrogen peroxide
  • Baking soda
  • White vinegar
  • Enzyme laundry detergent
  • Stain remover spray (like shout or resolve)

Step By Step Process To Remove Cat Period Stains

  1. As soon as possible, rinse the stain with cold water to remove as much of the blood as possible.
  2. Apply a small amount of dish soap directly to the stain and gently rub it in.
  3. Soak the garment in a mixture of 1 part hydrogen peroxide to 3 parts cold water for 30 minutes.
  4. Mix a paste of baking soda and cold water, and apply it to the stain. Allow it to sit for 30 minutes.
  5. Rinse the garment thoroughly with cold water.
  6. In a spray bottle, mix equal parts white vinegar and cold water and spray it on the stain.
  7. Wash the garment in cold water with an enzyme laundry detergent, following the instructions on the detergent's label.
  8. Check the stain before putting the garment in the dryer, if the stain is still present, apply a stain remover spray and let it sit for 5-10 minutes before washing the garment again.
Note: Hot water can set the stain and make it harder to remove, so it's important to use cold water throughout the process. Also, it's better to wash the garment alone or with similar color clothes to avoid color transfer.

In Brief

Cat period blood can be a dark brown color and contains a protein called fibrin, which can make it more likely to stick to and stain fabrics. To remove the stain, rinse with cold water, use a combination of hydrogen peroxide, baking soda, dish soap, white vinegar and enzyme laundry detergent. Use cold water throughout the process and check the stain before putting the garment in the dryer. If the stain is still present, apply a stain remover spray before washing again.
