You could be right Patsy, but we have catnip plants in the garden, and while visiting neighbours' cats roll in it and get spaced out, our Siamese don't seem interested! Maybe there's a Thai plant equivalent we don't know about. I've looked up Feliway, and it lists 'female feline pheromones', but these must be synthetic, and I can't discover what else is in it. As it's diffused around the house, I'm not sure if it's a good idea. I see that you had a 'Misty' too!
