Almost always one of our kitties is up on our bed by 11:00 at night. So when I woke up at 1:00 am and none of the three were with us I groggily went downstairs and was met with the terrible carnage of catnip all through the kitchen! One of them had gotten into the cupboard which had an unopened bag of catnip. It was a 1 oz bag which in fact is a large one. Finely ground catnip behaves like wood ash ie so light and so able to get in and on and under everything. It took me an hour to vacuum and wash the floors and still it is around as the cats tracked it everywhere. Incredible.
