Pure isomer … Cypermethrin is very toxic to cats which cannot tolerate the therapeutic doses for dogs. This is associated with UGT1A6 deficiency in cats, the enzyme responsible for metabolizing cypermethrin. As a consequence, cypermethrin remains much longer in the cat's organs than in dogs or other mammals and can be fatal in large doses. In male rats cypermethrin has been shown to exhibit a toxic effect on the reproductive system b…
