It would be so nice if I could explain to my cats thusly: "Yes, I know it's stinky stuff and you really don't like it, and I know you can see me coming a mile off with the horrid stinky stuff, and I know you'll hate me forever (or at least for half an hour), but that was a flea so you need the flea treatment." Ho hum. Trauma over now, so it can't have been that bad.
