Wicker furniture combines both beauty and economy. Beautifully woven wicker furniture can add a touch of class to any area while remaining one of the more inexpensive options for both indoor and outdoor pieces. Wicker is quite long lasting if maintained. Exposure to the elements and cat claws are two of the most common enemies to this type of furniture. If you see damage to your wicker, however, don't throw it away. Chances are it can be repaired with a little creativity.
Assess the damage that your cats have caused. If it is light and the scratches are not too deep, there is a good chance it can be sanded away. Simply take a piece of fine-grit sandpaper, and rub it gently over the damaged area. Once the damage is no longer visible, coating it with a lacquer or varnish.
For deeper cracks and groves, treat the surface with linseed oil. Cover the damaged area with the oil. Once finished, let the piece of furniture sit for a day or two so the oil becomes fully absorbed into the fibers. Wipe off any excess oil, and allow the chair to dry. Linseed oil replaces lost moisture and can help disguise damage caused by house pets.
If the cat has been using the piece of furniture as its scratching post, some of the fibers you may need to replace some of the fibers. This can be accomplished as long as the weave isn't too complex. Wicker strands are available at most craft and DIY stores. Try to purchase one that matches your piece closely. Weave the strands in following the design either on the furniture or example pattern. If several strands are needed, work one small area at a time
If the cats have caused extensive damage requiring several strands to be replaced, take the furniture to a professional--especially if it involves a large area.
Remember that linseed oil is flammable. Use caution when applying it to furniture.
