Review on Say Goodbye To Cat Tension With ThunderEase Multicat Calming Pheromone Diffuser Kit - Powered By FELIWAY! by Christopher Scales

I've always used the feliway multi cat diffusers. They work great. Thought I'd try these ones. I'm not sure. The cats are happier but one. She peed on the recliner and the diffuser was 2 feet away. It was only plugged in for an hour. So I waited. Then after some time.I waited. She peed in a closet upstairs. Another diffuser was 4-6 feet away. I'm sure it's just her. She is due to be spayed soon. That should help. At least she's happier and so are the other cats. I reordered the refills because they cost less than the feliway brand. I'll update when she gets spayed and see if that was the real issue. She has stopped the scratching on furniture though.
