A world beyond?

I walked into the room where my human washes, and had a wander round.
I sniffed lots of things.

Then I spotted that the strange thing, which usually has its doors closed, was open.
And I saw this...


























What is it?
Is it a portal to another catty world?
Does it lead outside?
Are there strange creatures beyond it?
Is there food underneath it?
Is it the gateway to a land of tuna?

I sniffed it.
I pawed it.
I meowed at it.

It would not reveal its powers to me.

I went to find my human, and meowed at him - to ask for his assistance.
He didn't understand, and gave me an ear scritch.
Idiot.

I had a nap, but shall investigate this strange portal again.
