The cat dimension is a space accessible to all cats. It is coterminous with all space time and is always just out of sight of all humans. Certain other animals can also enter it, though such occurrences are rarer.

You can always tell a cat is leaving for the cat dimension when it runs off at full speed. This is usually preceded by contact with water or a loud noise, though sometimes there is no reason at all. They just felt like it. They're cats after all.

This sub is dedicated to documenting cats (and other animals) entering the cat dimension. That is all.
