We also have 2 cats. I plan to lay chicken wire on top of the soil.
Is this a good method? Has anyone tried a motion detector water

Yeah, and it works for fine on five cats and two dogs. You don't even
have to leave it on all the time. Once they know it's there (2 days
max), occasional use, just to show the colors, so to speak, is
sufficient.
