How can i teach my cat to stop scratching furniture inside my house? Keep in mind that i live in the countryside, the cat can go outside whenever it wants and it can scratch stuff outside.

There are several ways to teach your cat not to scratch furniture inside your house:

    Provide a Scratching Post: Offer a scratching post to your cat, and place it near the furniture they have been scratching. Encourage your cat to use the scratching post by using toys, treats, or catnip.

    Trim Your Cat's Nails Regularly: Trimming your cat's nails regularly can help reduce their urge to scratch. Make sure to use a proper cat nail trimmer and be gentle to avoid injuring your cat.

    Discourage Scratching: If you catch your cat scratching furniture, gently pick them up and place them near their scratching post. You can also try using double-sided tape or aluminum foil on the furniture to make it unappealing for your cat to scratch.

    Reinforce Good Behavior: Reward your cat with treats, praise, or extra playtime when they use the scratching post instead of furniture.

    Provide Mental and Physical Stimulation: Make sure your cat has plenty of toys and opportunities for play and exercise. Bored cats may be more likely to engage in destructive behavior, like scratching furniture.

It's important to remember that scratching is a natural behavior for cats, and it's better to redirect their scratching to appropriate objects rather than trying to eliminate it entirely. By providing an acceptable alternative, you can help your cat feel satisfied and keep your furniture safe.

But how can I redirect his attention, his greatest pleasure seems to destroy the furniture? What concrete things other than what you mention can I do to provide mental and physical stimulation?

Buy a fishing rod with feathers or a small mouse on the end, and encourage your cat to sneak up on it, then chase and catch it. This is how many cats discharge negative emotions. Another good idea to discourage cat from scratching furnitures is to buy a special spray repellent. It is safe for your cat, but has an unpleasant smell, so spray it on the place your cat has been scratching so far. On the other hand, you can grease or spray the scratching post with catnip (they are available in tablets, powder, spray) - most cats will immediately feel encouraged to use such a place. It's also pssible that this behaviour is induced by stress.There are special medications available both in the form of dietary supplements, as well as sprays or diffusers. Their purpose is to provide a sense of relaxation and reduce the physical symptoms of stress. If none of this helps you should contact a cat behaviourist  or a vet.
