Scratching is normal. Cats scratch to stretch, mark territory with scent glands in the paws, and maintain claw health. The goal is not to eliminate scratching but to redirect it to acceptable surfaces and protect valued furniture while you train the habit.
Start by adding several sturdy scratching posts and pads in places your cat already chooses, such as near sleeping spots or along pathways to the sofa. Offer both vertical and horizontal options with sisal, cardboard, or carpet textures and ensure posts do not wobble. Reward your cat with treats or play when they use the right surface.
Make furniture less appealing with tight-fitting covers during training, double-sided tape designed for cats on targeted edges, or pheromone diffusers if your veterinarian agrees they fit your situation. Avoid declawing; it is painful, alters how cats walk, and is widely discouraged by major veterinary organizations.
Soft plastic nail caps applied by you or a groomer can reduce damage if your cat tolerates them. Trim nails every few weeks to blunt tips. Never punish scratching after the fact; instead interrupt gently and move your cat to the post, then reward.
If scratching is sudden, intense, or paired with urine marking or hiding, stress or medical pain may be involved. Rule out illness with your veterinarian while you improve enrichment and scratching real estate in the home.
