I was beginning to think it was only "me", too!! This week I applied it to her in 4 applications, 4 days in a row. I guess that is as good as applying it all at once. We have an outside cat that adopted us around 8 to 10 years ago. I'm sure she prowls the neighborhood. I don't see how we can avoid fleas.
You're lucky to not have fleas. We have never had any either but since the dh didn't spray this year, I'm afraid we may have some.
She scratches a little here and there.
Well, it's good to know I'm not the only one that has tried Vectra and has had this problem! Thanks for replying.
