It's nice to know we're not the only family with pets who react with psychosis to moving to a new house. When we moved the (then) five cats, it resulted in an outright palace coup. In the old place, since Magrat was the eldest cat she was the alpha cat. However, as a kitten, Ellen had taken Goblin outside several times and so youngest, and therefore most junior, cat Goblin was quite used to the idea that the sky could disappear into clouds and the world was bigger than a 900 square foot apartment. The others, not so much, and while they spent the next two weeks twitching in their carriers Goblin laid claim to the whole house. The world was never quite the same again for Cat, the Eldest (Magrat), although they eventually managed to negotiate an uneasy truce.
Ellen was convinced Coconut, the cat that almost literally was born and raised in one, small, place, would ever be right again. Eight years later it's like they've never lived anywhere else. Now that Goblin and Coconut have the entire house to themselves, they seem to spend most of their time being startled by, or plotting the demise of, the feathered "tiny green fud that is much less dangerous than the big green fud" that has been thrust into their lives.
