They're more susceptible to pyrethoids than some other mammals but so much that the low concentrations (typically 0.5-1.5%, for the product in

What will definitely harm them, and what is generally the issue of discussion when talking about cats and pyrethoids are topical flea control products, which are things like this:

It would be nearly impossible to deliver the same dosage to a cat using sprayed pesticide; you would have to spray the cat directly and repeatedly or try to get them to ingest a good amount of it. It would be especially unlikely that you would hurt your cat if you're just spraying your clothing or yourself while going outdoors rather than treating your house.
