Camphor balls are harmful to cats, mainly because they contain toxic substances such as naphthalene and paradichlorobenzene. When cats come into contact with or ingest them, they may experience poisoning reactions such as vomiting, diarrhea, and convulsions. They can also damage the cat's red blood cells, leading to diseases such as anemia, liver damage, and jaundice. Therefore, owners should place camphor balls out of the reach of their cats.

Besides mothballs, many commonly used medicated oils and ointments, such as peppermint balm and white flower oil, contain camphor. Therefore, pet owners should be careful when using these medications to prevent their cats from licking them during affectionate moments!
