Cats on mats

[Catherine]

Cats are great a camouflage.  These cats are hiding in plain sight on floor mats. They are right there, but can you see them? 
They are almost invisible.

The cat on the stairs is strangely well hidden. Some of them are really hard to see. I wonder if these cats are laughing at us because we can't see them.
It would be a typical cat move to do that.
