i have tried a feliway diffuser (2), but when they ran out i have not replaced them because my back door and some times my front door are open during the day, I always have an upstaires landing window open, so I believe the levels of the cat phemorones never build because of the fresh air that I always like circulating - I am paronoid about cooking and cat smells, and also so the cats can come and go as they please.
I ve not heard about this putting resue remedy on their ears can I have more info. please?
