In our new (temporary) home, we have created some partition walls to keep the pack from wandering too far and getting into things that could be harmful, especially since three can't see. Also, they need to be kept away from the cat kibble and the (ever so tempting) litter box.
The cats have two little escape routes, little cat doors. They had to be made small so that our smallest (and most determined) Brook wouldn't be able to get out.
Of course, since Breeze loves the cats, especially Elsie, she just had to check and "see" if she was around.
|"Elsie, you out there?"
Once Brook realized that there was something that her head could fit in, she had to try and get her body through.
If her shoulders were any narrower, she would have made it through.
