I have found that a good solution to digging at the carpet is to use the HEAVY-DUTY carpet runner from Home Depot (or similar). NOT the plastic stuff. It's very tough indoor-outdoor carpet, thin with a rubber back. I bought a bunch for less than $3 / yard. It's about 3' wide. If you have decent but not too thick carpet padding, you can often actually use carpet tacks (which are actually small nails) to tack it down around the edges, every 6" or so. It doesn't hurt the carpet and if you tack it down well, the heads of the tacks make a little indentation so they're below carpet level and your feet never touch them. They can dig at that all they want. Fred actually managed to dig through one in a doorway after many months of working at it. But what the heck. It was about $2 to replace. Better than replacing $1000 worth of carpet. The link below is a picture of the Home Depot heavy-duty carpet runner in one of the doorways here. The little white things are Radio Shack cable staples (two small nails with a plastic piece between). Those are to make removal easier. But even with the plastic part, if your carpet padding is good the nails hold them below the surface level of the carpet so you don't feel them with your feet. If your carpet padding is not so good, you can use carpet tacks rather than cable staples; they're just a bit harder to remove. http://s23.postimg.org/myrmag449/IMG_20140225_222617942.jpg Lonny Eachus [Posted in FML 8054]
