The above. I had to watch the vid many times slow to figure what the heck it was. It looks like a dog bed for a chihuahua. Crowley goes into the dark an something furry bigger then him is in there, fight or flight. An the bird, cover that end of the cage at the minimum. The carpet gives off gas stop using it. Paper towels work fine.
You keep stating his room. Do you use two cages for him? If so please stop, as soon as Crowley gets settled in it's change 1,001. Again, the bird is not helping.
Now, what does Crowley weigh an any other snakes in the house? How cold is it in Canada now?
