Why cats scratch sofas:
1. Loneliness and boredom, seeking your attention. Firstly, cats can indeed be lonely and bored at home sometimes. After playing their pre-arranged activities, when they have nothing else to do, they will choose to scratch the sofa.
2. During the seasonal shedding season. Of course, from the perspective of seasonal shedding, the cat's strange scratching behavior on the sofa at this time is mainly an unconscious physiological reaction.
3. The sofa's material is suitable for its claws. When no one is home, it chooses to scratch the sofa, but avoids wooden doors or furniture. This suggests that the sofa's material is relatively suitable for it to hone its claws.
4. The sofa has a pungent smell. Since cats like to eat meat, which is something we can tell, some leather sofas have a smell similar to meat, making them quite pungent. 
Can I cut my cat's claws?
1. Cats' claws need to be trimmed regularly, preferably once a month, to prevent them from growing too long and damaging furniture or injuring themselves.
2. Owners can buy special nail clippers for pets at pet supply stores to trim their cats' nails. Each time you trim them, be careful not to cut the cat's quick.
