Permethrin Toxicosis

Products Containing Permethrins

• Permethrins are found in many types of dog-care products, including shampoos, sprays and spot-on treatments, which are geared to preventing flea infestation. Though these products are usually clearly marked for use on dogs only, many people make the mistake of thinking that products created for small dogs can be used on cats. Others believe that using only small amounts of the product won't harm their cats. But this can be a fatal mistake. Permethrins, even in small amounts, can be devastating to a cat.

How Permethrins Work

• Permethrins kill fleas by attacking their nervous system. In most animals, these toxins are quickly broken down by the liver and no toxins ever threaten the animal's health. Cats, however, cannot break down this toxin quickly enough and are highly sensitive to this particular insecticide. Only products specifically designed for cats should be used on your feline friend.

Signs of Toxicity

• Signs of permethrin toxicosis typically occur within 72 hours of exposure. A cat exposed to this toxin will have full body tremors or even a seizure. Other signs of toxicosis include hyperexcitability, depression, vomiting, anorexia and death. Pet owners should be aware that even a cat that hasn't been treated directly with permethrin can be harmed by it. A cat that grooms a dog following the dog's treatment or a cat that rubs up against a treated dog can develop these symptoms.

Treatment

• Cats that exhibit signs of permethrin toxicosis should be treated immediately by a veterinarian. Vets may first treat the tremors by placing the cat on an intravenous drip and, once the cat has stabilized, will bathe the animal thoroughly using a mild dish washing soap to remove any remaining toxins. The cat's temperature will also be closely monitored, as animals with permethrin toxicosis often suffer from hyperthermia. Cats that are treated promptly typically have a good prognosis and can generally return home within 24 to 48 hours after treatment begins.

Prevention

• The best prevention for permethrin toxicosis is educating pet owners to carefully follow product guidelines. The American Veterinarian Medical Association has recommended that products be clearly labeled to explain to consumers the potential threats of misusing such products. Most flea treatments are made for a specific animal and specific weights. If guidelines are carefully followed, permethrin toxicosis can be avoided. If your cat begins exhibiting signs of toxicosis, the faster you get the animal to the veterinarian, the better the outcome.
