Beeps has to stay in his cage when we eat dinner, as us eating is one (of many) things that triggers him to fly over and bite/attack us. It's far easier to cage him and prevent a bite than duck his attacks and risk throwing food all over the room.
Yesterday, Rocky had been climbing over Beeps's cage and opened up Beeps's door. He'd left the scene of the crime before I could take a picture. Beeps wasn't paying attention to the blatant escape route; preferring to use the less-effective cute method:He did get out as soon as dinner was complete.
