Is there something about this chemical that is particularly dangerous to cats?
Permethrin SFR 36.8% contains permethrin which has been shown to be toxic to cats but is tested and approved for safe use on dogs. Products with the same active such as Advantix are not formulated the same so are not universal for how they are used. The inerts and formulation can vary from product to product.
