My friend was going to throw out her cat because he could not get used to the litter box, he yelled, scratched, damaged furniture, climbed on tables. I felt sorry for the cat, so I took him in. Yeah, he was a problem. But it all worked out. It turned out that to make him go to the litter box, you just need to change the litter. To stop him screaming, you had to neuter him. To keep him from climbing on the table, you have to pour drinking water in a bowl and put it separately from the food. To prevent him from spoiling the furniture, you should buy him a scratching post. To avoid scratching, you need to trim his claws. And in general, you have to play with him. 15 minutes of rope or bow play will guarantee that he'll sleep. After a month, even less, it turned out that this is the sweetest and most gentle cat. A friend came to visit me once and did not recognise her cat. She said: "Give him back to me, he turns out to be normal.
