Well, I need some help. My hubby built our kids this huge sandbox but the neighborhood cats have finally found it. lol We have a chain link fence around our whole backyard but they probably sneak in under the gate. There's nothing worse than playing out there with the kids only to dig up what some cat has left behind. Can anyone give me some ideas to keep them out? It's too big to cover unless I buy a large size tarp but then that's kind a pain too. Help!!!!
