Devon Rex kittens in class judging at the 2018 CFA International Cat Show held in Cleveland, Ohio, USA.

The judge is Rachel Anger.

In these clips you can see the typical stubby Devon whiskers, they simply break off where they're thin seems to be part of the Rex thing, variable hair width.

And variable hair density too, from thickly wavy to Sphynx like, coming and going pretty randomly far as I could tell, though some Devons do have a more permanent coat or lack of coat.
