Glad to see Prop. 65 is working
I have felt that flea collars are bad - I tried them in Bakersfield years ago, but noticed that I got headaches from holding my cats, so I cut them off & never used them again. I used to give my cats saline baths; all the fleas would go to the top of the cats' heads & I'd pick them off there. Now I'm in a "dog-flea free" area, but would use AdvantagePlus for cats, if they were allowed out.
Maybe, since some people won't/cant stop using the collars for the sake of their pets, they will for the sake of the children. And sometimes it does take lawsuits to stop companies from not trying to do better
