Q: I found a spiked plastic mat that discourages cats from rolling around in my perennial flowers, but it seems pricey. Do you have a more economical way to scat the cats?

A: How about using sweetgum balls among the plants? I can offer you all you ever need! Or try cutting coat hanger wire into 4 inch lengths and pushing lots of them halfway into the ground in your bed to poke the cats when they roll around.
