I have my year old male veieled in my room and he is about ten feet away from my 26" TV. I am out of my room all day, but when I come back here at 8, I want to watch TV or play video games. I noticed that he would run all around his cage when I had the TV on, so I hung one of my shirts in front of the cage as a visual barrier. That seemed to help! I think he was just able to make out the shapes and the movement of the TV and that stressed him out. My question is, is the barrier nessasary? Thanks a bunch guys!
