Figure 2. Cat ectoparasiticide products.

Responses to the question: “During the last 12 months, what is the main flea product used on your cat?”. n = 353, respondents that had not treated their cat in that time (n = 36) or applied an unrecognised/ alternative treatment (n = 7) are not included. Main active ingredient = main flea adulticide ingredient, determined by mass. Note that active ingredients beyond the main flea adulticide are not displayed here (for example, flumethrin in Seresto collars). Further information on number of respondents and active ingredients is provided in File S2.
