Cats with seizures from Seargants Flea and Tick Drops for dogs?

We have 2 cats and each was given aprox. 1mg of Seargants flea & tick drops for dogs about 4Pm today, (10 hours ago). Both have been very sick and have had seizures. We thought the medicine was for cats. Both are about 5 years old. What can I do for them until a vet is open?

    Take your cats to an emergency veterinarian immediately! If the seizures are not treated quickly enough it can result in permanent brain damage and death. It is likely that the product you applied contained permethrin which can be very toxic to cats. Not only can the product induce seizures, it can also cause high fevers and damage to the internal organs such as the kidneys. The best chance your cats have for survival is to seek medical care for them immediately. Your veterinarian will give your cats injectable medications to help stop the seizures and your pet may need to be hospitalized for several days before completely recovered. In the future, make sure that you read the labels of all medications and flea products before administering them to your pet. When in doubt, call the manufacturer number on the packaging or call your local veterinarian with questions. Rebecca, DVM

    PJ is only two years old so this is not an issue of age. She has always been "challenged" in that she doesn't appear to have normal coordination and balance of other felines I've had. She overcompensates on her jumps in order to make certain that she lands on something. This morning is unusual ... and when we pick her up she cried loudly as if it hurts but we can't tell where she hurts. We cannot afford "tests" so we just don't know if this is the "end" for her or not. Thanks for advice
