Human: How do you know if your cat is depressed? Assistant: 
Cats are known to be very independent and aloof. They don’t show their emotions easily, so it can be difficult to tell if they are feeling down or depressed. You may notice changes in behavior such as decreased activity, sleeping more than usual, or avoiding contact with people. If you suspect your cat might be depressed, talk to your veterinarian about how to best assess the situation.
