A cat.I'm not sure I want to see what a cat would use to seal up a hole.
I'm not sure I want to see what a cat would use to seal up a hole.You seal the hole using the cat. Because it's a mouse hole, mice will try to enter it and end up walking directly into the cat's mouth, thus also meaning the cat does not require feeding.
picsIt's just a hole in a wall. Nothing particularly special about it.
i always thought mouse holes were just a cartoon thing
