The funny thing is that some medieval bricklayer made a conscious choice here, he could have put that brick paw-print down and made a flawless floor. Now, here we are getting a chuckle out of some unknown bricklayer’s little gag centuries later.
I’m also wondering if those are not fake prints. They look pretty deep. I don’t think a cat walking on drying bricks would leave such deep marks.
To me they look like easter eggs left by the brick layer.
Maybe they’re deep because of water erosion from rains over a thousand years, those bricks look pretty polished.
As a cat owner, this doesn’t even look like a real print. It’s too deep. Most likely a manufactured print done as a gag by whoever made the bricks.
Wouldn’t he have needed to change the brick? If you flip it then it wouldn’t fit there any more since its shape is asymmetrical.
