The use of human showers by dogs and cats is not recommended, as human showers usually contain chemical components and spices that are unfriendly to the skin of cats.

The pets bathe with a man.
Skin irritation: Human bathing usually contains strong chemical substances, such as sulphate and artificial spices, which can lead to skin sensitization or irritation of cats. Dogs and cats have thinner and more sensitive skins than humans and therefore may react negatively to the contents of human baths.
Hair dry.
Hair problem: The use of human bathing can destroy the natural oily balance of cat hair, resulting in dry, fragile and breakable hair. Dogs and cats can also maintain the health of their hairs by licking their own hair, and bathing in humans can undermine this balance.

Same ingredients.
Toxicity risk: Some human ablution may contain components toxic to cats, such as phenol compounds, alcohol or other chemical substances. These substances may negatively affect health through skin absorption or cat feeding itself.
If you need a pet to bathe, you have to choose a shampoo or a bath for a pet. These products have been developed to take into account the skin sensitivity and needs of the pets and do not contain elements harmful to cats.
If you have any doubts about cat's skin health or bathing behaviour, please consult veterinarians who can provide the most professional advice and guidance. Veterinary will recommend a suitable cat bath product and tell you how to clean and care for the cat's skin and hair.
