Does Bengal Cat Scratches?
As with any cat, it is very normal for Bengal cats to instinctively scratch their belongings to mark their territory.
However, since these cats are not so far from their wild roots and are large domestic cats, they can cause more damage to your furniture and curtains in scratching.
Regularly, at intervals you deem necessary, it will reduce the damage somewhat, but I recommend using scratching posts and toys. Even if he goes out, he will continue to do this when he comes home, so placing scratching platforms at the entrances of the rooms where he spends the most time will help to minimize the damage.
If you buy the materials as a puppy before they start scratching the seats, you have a better chance of intervening before this behavior becomes established. You can get valerian, also called “Catnip”, to attract his attention. If you apply it to the scratching toy in dried form or as a spray, you will see how effective it is.
