Is Chlorine Bad for Cats?


If you’re a cat parent or owner, you may have wondered whether chlorine is bad for cats.

Cats are curious creatures, and they often come into contact with various substances in their environment.

Chlorine is commonly found in swimming pools, cleaning products, and even tap water.

In this blog post, we will explore the effects of chlorine on cats and whether it poses any risks to their health.

What is Chlorine?

Chlorine is a chemical element that is widely used for its disinfectant properties. It is commonly used to treat water in swimming pools, as well as in cleaning products and bleach.

Chlorine kills bacteria, viruses, and other microorganisms, making it an effective sanitizer.

How Do Cats Come into Contact with Chlorine?

Cats can come into contact with chlorine in several ways. One common way is through tap water.

Most municipal water supplies are treated with chlorine to kill harmful bacteria and ensure the water is safe for consumption.

Cats who drink tap water may be exposed to small amounts of chlorine.

Another way cats can encounter chlorine is through swimming pools. Some cats are known to be attracted to water and may jump into a pool or accidentally fall in.

If the pool is treated with chlorine, the cat will be exposed to the chemical.

Additionally, cats may come into contact with chlorine through cleaning products.

If you use chlorine-based cleaners in your home, your cat may be exposed to the chemical if they walk on surfaces that have been cleaned with these products.

Is Chlorine Harmful to Cats?

While chlorine is generally safe for humans when used in appropriate concentrations, it can be harmful to cats if they are exposed to high levels of the chemical.

Cats have a different physiology than humans, and their bodies may react differently to certain substances.

Exposure to high levels of chlorine can cause irritation and damage to a cat’s skin, eyes, and respiratory system.

Cats may experience symptoms such as coughing, sneezing, wheezing, difficulty breathing, and eye irritation. In severe cases, exposure to high levels of chlorine can be life-threatening.

What to Do If Your Cat is Exposed to Chlorine?

If your cat comes into contact with chlorine, it is important to take immediate action to minimize the potential harm. Here are some steps you can take:

  1. Rinse your cat with clean water: If your cat’s fur or skin has come into contact with chlorine, rinse them thoroughly with clean water. This will help remove any residual chlorine and reduce the risk of irritation.
  2. Flush your cat’s eyes: If your cat’s eyes have been exposed to chlorine, gently flush them with clean water. This will help remove any chlorine residue and soothe any irritation.
  3. Monitor your cat for symptoms: Keep a close eye on your cat for any signs of respiratory distress, such as coughing, wheezing, or difficulty breathing. If you notice any concerning symptoms, contact your veterinarian immediately.
  4. Provide a calm and stress-free environment: Exposure to chlorine can be stressful for cats. Create a calm and quiet space for your cat to relax and recover from the exposure.

Preventing Chlorine Exposure in Cats

Prevention is key when it comes to protecting your cat from chlorine exposure. Here are some tips to help minimize the risk:

  1. Use a water filter: Consider using a water filter to remove chlorine and other impurities from your cat’s drinking water. This will ensure that your cat is not exposed to high levels of chlorine through tap water.
  2. Keep your cat away from swimming pools: If you have a swimming pool, make sure it is securely fenced off to prevent your cat from accidentally falling in. Additionally, keep an eye on your cat when they are near a pool to ensure they don’t jump in.
  3. Choose cat-friendly cleaning products: Opt for cat-friendly cleaning products that do not contain chlorine or other harsh chemicals. There are many pet-safe alternatives available that are just as effective at cleaning.
  4. Provide fresh air: If you use chlorine-based cleaners in your home, make sure to ventilate the area well to minimize your cat’s exposure to the chemical.


While chlorine can be harmful to cats if they are exposed to high levels of the chemical, taking preventive measures and promptly addressing any exposure can help protect your feline friend.

It’s important to be aware of the potential risks and take steps to minimize them.

If you have any concerns about your cat’s health or exposure to chlorine, consult with your veterinarian for guidance.
