Early Xmas presents?

Riley left us a nice present on the rug. Unfortunately it's not the type of present you can't wait to wake up and open. Originally we had bought those cat pheromones so they wouldn't scratch on the door or leave presents. The cats still scratch on the door although now at 6am instead of 4 or 5am and they haven't left us any gifts in a long time. So it seems that the pheromones don't quite work. The pheromones did run out during this last episode but I think the gift was Riley getting even for not being fed until 7am.
