UPDATE: I was dismayed to realized that although Feliway plug in says it lasts for 6 weeks, after only THREE weeks the container was about empty so I had to replace it!!! There should be some way to regulate the amount released but apparently there is not. (I thought maybe the vents were opened all the way and that was why it evaporated in half the time the box indicates.) I'm going to contact the company, because it says right on the box that it should last about 6 weeks, and at $24.00 a refill, I can't afford changing the refill every 3 weeks. I really don't know if it has had any effect on my cats. Debra has been using the litter box consistently (knock on wood!) even though experiencing a urinary tract infection for which she is on meds now. Her pees were very tiny and frequent so the vet did an in-house urinalysis and also sent out to a lab and diagnosed UTI. No crystals were found, nor any other kidney problems.

Deb, I hope you are having a positive experience with Feliway, and your Husky story made me smile!
