The stuff I have - I spray a teeny bit on Oscar's collar in the morning, and sometimes at night.

I listed the ingredients and the percentages so you could check yours and see if they are at least as potent as the one I have.

The Analogue Feline Facial Pheromone - I love that phrase, why don't they just say SYNTHETIC? is the most important one. Dissolved in alcohol. No wonder Oscar gets happy!
