Which ingredients are bad for cats?

There are a lot of ingredients to avoid when buying cat shampoo. Using products containing these ingredients can cause a variety of issues, including irritation, allergic reactions, dryness, flakeness, and skin pain. When they get into their eyes, this causes pain and irritation.

Some ingredients, such as phenols, are toxic to cats and can cause some serious consequences, including liver and kidney damage and neurological problems. Unfortunately, like other toxic ingredients, phenols can be fatal for cats as well.1 This is why it is so essential to check the label before using new products on your cat.

What about essential oils?

Cat-toxic essential oils, like tea tree oil, are commonly used in cat shampoos, but are highly diluted. As long as it is a product specifically formulated for use in cats, the concentrations are very low and should not be considered toxic, but it is highly recommended to check with your veterinarian first. This applies to new shampoos used on cats.

Never apply essential oils to cat skin except for veterinary approved products specifically formulated for cats with diluted concentrations. Topical application or oral ingestion is fatal.

Can I use human shampoo?

No, human shampoos are not safe for cats and should not be used for bathing. For one thing, human pH balance is different from cat pH balance, and human shampoos are formulated to be more acidic than pet shampoos. Cats are more sensitive because they have less skin layers than us. Using human shampoos will interfere with the pH balance of your cat and cause dry skin.

Furthermore, many of the ingredients found in human shampoos (including the list above) are not safe for cats. Sodium sulfate salts, parabens, artificial fragrances and colours are some of the ingredients commonly found in human shampoos, all of which can irritate cat skin.

Can I use dog shampoo?

no. Some ingredients used in dog shampoos are safe for dogs, but not for cats. For example, permethrin, an ingredient used in flea control products for dogs, is toxic to cats, like some essential oils. Therefore, do not use human or dog shampoos on cats. The only exception is shampoos formulated with both cats and With the dog it is clearly marked that way.

    Final Thoughts

    Again, most cats don’t need to bathe, but if yours is, it’s essential to do your research and carefully check what’s in the shampoo you use in them.

    Not all brands list their ingredients. According to the American Pet Products Association, pet shampoos are not “generally” necessary. It is highly recommended to avoid such products and stick to a reputable and trustworthy brand that your vet lists the ingredients.
