Hi Janis, I don't know about this and cats, but will say one word of caution,
just in case. I remembered I did have one problem with one dog with advantix.
He was a pug and when I gave him the med, he all of a sudden came down with
very difficult breathing. I could not give him that med. It somehow affected
his breathing system as if it gave him asthma. The other dogs tolerated it
fine, it was just something that affected him for some reason. Allergy?? So
just be aware of that if You switch, watch them for an hour or so after
applying if You'd like.
