I do believe that [for me] this is one of the happiest gatherings of all time.
Now, about those pheromones. - quote: When a cat feels safe and comfortable in its environment, it rubs its head against the furniture, the corners of walls or the bottom of the curtains, leaving a substance called the facial pheromone. This pheromone, specific to cats, conveys a message of security and well being. The plug in thingy that we're using, is a synthetic copy of this pheromone and is proven to comfort cats, helping them to cope with stressful situations...such as meeting with a nasty incident in the forest and limping home with a bitten foot and drenched to the bone.
It is non-sedative and has no effect on the staff of said cat.
Rory appears to be "chilled" at the moment. But then, apart from the episodes when he goes into a "flat spin" he has never given us cause to believe that he's stressed. However, I googled his symptoms and discovered lots of info' which suggests otherwise. He sends purrs to his fans.
