A cat doesn't scratch to give you grief. A cat scratches because it's a form of exercise for the cat's muscles from the claws right through to the legs, shoulders, and down the back. In addition, scratching also sharpens the cat's claws and cleans the exterior sheath. Cats also scratch to scent-mark territorial areas with their paws, which have scent glands usually indistinguishable to humans, but very distinct to other cats, dogs, and many other pets and animals. and be understanding. You love your cat and the precious bond both of you share. Cats know when you care and will reciprocate. They will do their best to please their human companions, provided they know they're supported and praised. Over time, with repeated loving practice, your cat should become used to leaving the furniture alone and using alternatives for their scratching. A scratching post is the answer to your scratching problem, but it will take time to encourage your cat to use it.  When purchasing the scratching post, there are some things to consider initially. Look for one that is at least as tall as your cat when he/she stands on his/her hind legs. Ensure that it is sturdy and cannot wobble when pressure is applied to it by your cat. Make sure that the scratching post isn't heavy and tall, or it may fall on your cat. Scratching boards and posts come in different sizes and uses. Some are flat on the floor and some are raised. Some are made of hemp. Try different types. It is better to have too many around, than not enough. Some cats prefer to scratch on a horizontal surface like the carpet. Orientate the scratch post horizontally or vertically to match their preference and they will be more likely to use it. There are cardboard, sisal, and carpet based options for horizontal surfaced scratching.   Whatever you choose, avoid anything fluffy. A cat's scratching post must be like tree bark (their natural scratching element), rough and coarse. Posts with sisal fiber rope wound around them are best, and the scratchier it is, the less inviting...
