I know Orijen does supply pet stores across America and also in Europe. So maybe you might be able to find it locally. That's weird about Haley leaving you treats after you give her enzymes. If only they would actually use the toilet...lol. What a good girl to leave it in the bathroom though.
I have a friend who is a teacher and had 3 big cats. Well one night she was home alone doing some marking in her dining room when from out of no where the toilet flushed. It totally surprised her and really scared her as she was alone. So she grabbed a baseball bat and went down the hall towards her bathroom just as the toilet flushed again. She swung open the door and there was her big cat balancing on the toilet seat watching the water swirl down the toilet...lol. He kept flushing it over and over again that night fascinated by the water going down. Eventually she had to lock him out of the bathroom and everytime she left home she had to make sure the bathroom door was closed as her water bill skyrocketed for a month or so there. I thought that was hilarious, but I can't imagine being home alone and then you hear the toilet flush...geesh what cat!
