Query: This will HARM your cat!!!!

My wife purchased this for out outdoor cat a last September. Last night we applied it again since we've seen a lot of ticks so far this month. Well today my wife called me in a panic stating our cat was now BALD where the medicine was applied between the shoulder blades and his skin was red like it had a chemical burn. Our cat is a male, about 10 years old and about 12lbs. He's a tough tom cat so I'm sure he'll survive this but PLEASE search the internet for other reviews of this product. Other cats have died! If it's possible for me to add a picture later I will do so but I would stay clear of this. We'll be purchasing a name brand from our vet next time. I wish we would have searched for reviews before we used.
