Shopaholic? Me?

I bought a ball pit for my kids which they love but I keep having to completely pack it away because of the neighbour hood cats who try to mark everything and I mean everything. So I thought about getting a ball pit cover but they are not easy to come by and when you do find them, they are expensive. It is not like I am after some hot tub covers just a ball pit cover. Maybe I will fashion some out of black garbage bags and duct tape. LOL!
