Can you spot the error hidden in this room?

On a quiet evening, the man in the image appears to be stretching out to watch TV and relax with his two cats. The scene is far from peaceful, however, as a closer look shows the room is seemingly full of logical mistakes. The plants look lush despite having no sunlight, the lights are on without being plugged in, and the TV is broadcasting a mix of unrelated animated scenes unlike any channel in real life.

The two cats seem more interested in plotting against their owner than watching TV. The cup of tea on the table looks like it has been cold for months. The man may be relaxing but the room is filled with odd details from the layout to the objects.

The picture seems perfect at first glance though it becomes more amusing the longer you look. Can you identify the most unrealistic element in this unintentionally humorous room?
