This is our third cat, Tetris, but the only one to attack the hamster cage. The hamster was in his little bedroom and he and the room went flying to the other side of the kitchen.
He wasn't hurt, but we don't know what he was thinking.
We put him in the cat's travel cage while we cleaned up the mess. Sandy put it back together wrong (Ha) and he got out a hole on the side. We found him and all is well.
