I have put bark down in the corner of my garden, intended to be the kids play corner. Instead, I've created a giant litter tray for my cat to crap in! Ideas for how I stop him?! My best idea at the moment is super soaker... But that seems a little harsh! He doesn't have an actual litter tray, which I could get if I thought he'd use it in preference... He's always gone outside but is 14 now and in the house a lot more. Any other ideas appreciated.
