Cats and small dogs are usually not an issue at all with cork floors. Large dogs, however, can damage the surface of almost any floor, especially hardwood.
Cork has the advantage over hardwood since it is resilient, absorbs impact and doesn't scratch or gouge as easily as hardwood. Protected by DuroDesign's MP765, cork also has excellent abrasion resistance.
Ultimately, your pet's good behavior and keeping their nails trimmed will help keep your cork floors looking beautiful.
