Rupert here, exploring on the Catio.
I strolled past the Isles of Avocado...
...to the mouth of the Forbidden Blue Cave...
...heretofore unexplored by this intrepid grey kitty.
Slowly I crept inside, mindful of any creatures that might be lurking there...
...and of which there were thankfully none.
It's not, perhaps, on the scale of finding the source of the Amazon...but satisfying, nonetheless.
