Catnip Caper

We received a free bag of catnip with our last purchase of cat food. I put it in the pantry by the kitty treats, not thinking twice about it.  We were watching a movie, and the pantry door was left open. We came upstairs after the show to find the cats literally rolling in the drug of their choice. Crush and Georgia were strongly affected by it, and although Sooty was covered in it, he didn't act any differently. Crush was a mess. He couldn't climb stairs and could barely walk, but worse was his breathing. He had clearly over exerted himself and we were worried. We cleaned up and it didn't take much time before things were back to normal. Thank goodness. Little trouble makers. What colour is the sky?
