Can I get a small FroYo, and a kitten...??

So I was in London with some friends today...and we ended up in Snog, near Covent Garden, for some frozen yogurt. This girl sat near us had a kitten with her!!! I've never seen anything like it!
This cute little kitten was sat on the girl's lap, with a little harness on - then it suddenly appeared by my friends and I...
Hygiene concerns didn't even enter my mind- I was just blown away by its cuteness, so I gave it a hug and let it sit on my lap for a little while :0)
Random, but super cuuute.
