One of my dogs, Loro, recently became a great fan of watching TV. Her most favorite TV program is 世界ネコ歩き (World Cats Walk) by NHK. She stares the screen, seems being fully concentrated, follows the cats as they move.
If I call her name, she only turns back with an annoyed look and goes back to the program. Sometimes she checks below or behind the screen when cats disappear. It is so cute to watch.
