Is this a cat with depression?

Changes in the life habits of the breeder or the cat, feeling depressed without getting enough interaction, being abandoned, changing seasons, and the death of a companion, etc., may all cause the cat's melancholy tendency! What are the symptoms of depression? Normally, I am very active and love to run around. Now I am either shrinking to the side or sleeping longer than usual. After getting up, I am also listless. The cat normally sleeps for an average of 12 to 16 hours a day. If you exceed it, you may need to pay attention.
