Can Bio Spot® dog products be used on a cat, and vice versa?

NOTE: NEVER use flea and tick control products for dogs on cats. Cats need special formulas. Only use products labeled for cats on cats. Cats and dogs can have adverse reactions to certain ingredients in each other’s products, including death. Though both products do contain etofenprox and methoprene, the dog and cat formulations are very different and each should be used according to the directions on the label. Bio Spot® brand tailors the products to fit the needs of each animal, and includes ingredients appropriate to each pet.
