Yesterday I applied Duke's first revolution vial. He's 10 months old and this was his first time every having it applied. Today I've noticed the fur around the skin I applied it to has turned light grey from black. Is this a normal reaction to the pesticide?
"Do not apply to broken skin—Revolution contains alcohol.
Stiff hair, clumping of hair, hair discoloration, or a slight powdery residue may be observed at the site in some animals. These effects are usually temporary and do not affect the safety or effectiveness of the product."
