Is it dangerous for cats to smell toothpaste?

Yes, it is dangerous for cats to smell toothpaste.

Toothpaste contains some chemicals that are harmful to cats, such as fluoride. If cats ingest toothpaste, it may lead to nervous system diseases, difficulty in concentration, heartburn, vomiting and internal damage. In the long run, it may even lead to urinary incontinence and even death.

So make sure that cats can't touch toothpaste. If your cat becomes interested in toothpaste, please stop it in time and tell it that it is not food. If the cat eats toothpaste, please send it to the veterinarian for examination and treatment in time.
