You may be asking why "Don't Cat"? It should actually say Don't Dog. Since we've moved and I've let the dogs be loose in the house we have had a little problem with excess hair on the couch and chair. The 100Y store has a solution for everything though. This is why we have "Don't Cat" now. This is a clever little product made to put in your garden to keep the cats from using it as a bathroom. The plastic webs have little plastic spikes that are uncomfortable to step on or lay on. They are not sharp enough to puncture skin as I found out when I did a test run with my own skin. Therefore they were deemed safe to use for project Don't Dog. Now when I leave the house I just put one on each cushion and the dogs stay off the furniture and use their own beds.
