The problem comes from a flea control ingredient called permethrin. While permethrin is safe on dogs, even small amounts of the ingredient on the skin of cats can cause deadly problems. Permethrin is common in flea and tick control purchased at grocery stores and big-box stores. Because of its popularity, Hartz flea and tick control products are often involved with feline permethrin toxicity. One of the few high-end flea and tick controls containing this cat poison is K9-Advantix.
Symptoms of permethrin toxicosis will manifest themselves within a few hours to three days following the exposure of your cat to Advantix. Symptoms include tremors, hyperexcitability, depression, loss of coordination, vomiting, seizures, twitching, lack of eating and death.Symptoms can develop in two to 48 hours. If your cat is exposed to permethrin, handle the situation as an emergency.
If you think your pet may be having a reaction to permethrin contact or transport your pet to your local animal hospital immediately.
