You run out of that positive scent marker, and they very well might feel the need to mark for themselves to make sure stress doesn't return. Point being, make sure you don't run out!
I used it when introducing my cats to my husband's cat 1 & 1/2 years ago & it worked wonderfully, even on 2 of my own cats that never seemed to get along before. I've stopped using it, and though my husband's cat now gets along fine with my cats, the 2 of mine that used to fight have started up again.
