I bought a large bucket of this stuff last winter. I've up until now survived without any ice melter but as I get older I feel I want more protection from icy spots. My cats don't go out in winter, and they wouldn't be walking where I used it even if they did, but I wanted something I didn't have to worry about tracking in the house.
The first picture shows what happened to the grass in the area I used it most heavily, which is right in front of my doorway. There's a drip from the porch roof that keeps that area solid ice all winter. It did a great job melting the ice, but look what it did to my grass. this picture was taken on May 17. Now, three weeks later, there is still no grass growing there.
