Hate to burst everyone’s bubble, but the cat was placed there deliberately to create a viral “news story” for publicity. Look how well-behaved and tame it is, and comfortable around a crowd of people. It didn’t just wander in.
And it looks like the ruse worked. By now, the designer’s beautiful winter collection has garnered 500 times the attention it would have, resulting in untold billions of additional sales as well as inestimable goodwill from gullible cat lovers everywhere.
