5. CERTAIN FLEA AND TICK PRODUCTS
Insecticide poisonings resulted in nearly 30,000 calls to the Poison Control Center in 2010, and a common problem involved using flea and tick products on the wrong species.
For instance, using a dog flea collar or topical flea and tick solution on a cat could result in seizures or even death for the cat. That's because just a few drops of a common insecticide used on dogs, called permethrin, could be lethal to a cat.
