Nadja started slipping on the tile. We have runners bits of carpeting all over the house now but she still manages to slip on uncovered areas so we bought these stick on sock pads with grippers. She has flat and fuzzy feet so the stickers fit better when we cut them into separate toes and main pad and stick them on. works pretty good but have to be replaced every two to five days. An added benefit is that they protect her pads from the hot pavers.
