Q. My cat licked his flea medicine and then started puking, will he get sick or die?
A. The best thing to do in this case would be to call the company's hotline. They have customer service providers available to help with toxicity concerns that you can talk to. The best with flea medicines is to get a high quality topical and follow the instructions included in the packaging. Frontline for cats will say to place the liquid between the shoulder blades. Placing the topical here will not allow for the cat to easily lick the chemical.
