kat, that's very interesting. I wonder if you've got different catnip to the stuff I grow? I grow Nepeta, but a smallish dwarf variety which doesn't droop all over the path like the larger ones. I've had Siamese for thirty years or more, minimum of three at a time, and never have I known a single one who was interested in the Weed. But my British Shorthairs always went mad for the stuff. I've always assumed it was because Siamese are different in some way. The Brits even used to rub the poor plants in the Spring, just as the tiny shoots emerged, killing a lot of it.
