Safety Tips for "Pour On" Flea Medications:
Use products ONLY as directed.
Never apply dog flea medication to a cat!
Apply medication to an area where your pet can't reach to lick.
Use the product recommended for the weight of your pet.
Do not combine flea products unless instructed by your veterinarian. Incorrect combinations can cause toxicity!
If you use over-the-counter medications, use only as directed. Take very special care to monitor cats and small dogs for 24 hours after administration if using a product containing permethrin or pyrethrin.
