Yes, he is now in a room to himself, but Snuggles with the help of my other dog can push the door open. This is the only room in our house where he can stay by himself without danger of sharp objects that we cannot take down.

Ocean has places to perch around the room, but we can't take them down, because they include little shelves. We feel he's safe up there but what I'm really wondering is why Snuggles would decide to attack Hedwig when she was in the cage. Is it a behavioral issue, or what?
