Review on KrohneTec Calming Collar for Cats & Dogs: Extended Anxiety Relief, Long-lasting Pheromone & Lavender Collar - Up to 60 Days by Bill Pulakanam

This collar works better than any cat calming collar. However, it is advertised as having a lifespan of up to 60 days, but ours didn't even last 30 days. Based on the price I wouldn't say it's a good buy. If it had lasted around 60 days as advertised I would say that's a lot, but if you need more than one due to multiple cats in the same household it would be prohibitively expensive to service and maintain the collars monthly. For this reason alone I can only recommend this article. If they were honest about how long the collars are actually worn I wouldn't feel cheated in any way. Other calming cat collars were advertised for a month. The only reason I went with this color was that unlike the others, they were said to last up to two months. Of course, other brands that don't last as long cost a lot less money. In fact I paid an extra month for the collar which I did not receive. I would recommend trying cheaper collars as they can only last about a month anyway. Why spend more than $15 when you don't need it?
