We have previously reported that some players believe that the badge in the visual image of The Witcher is neither a wolf nor a cat, but is almost consistent with the lynx school designed by fans.
Marcin Momot, global community director at CD Projekt Red, replied with a meaningful "nod" emoji to the player's conjecture.

Today, CD Projekt Red officially confirmed to foreign media that the shape of the new Demon Hunter badge is a lynx. Robert Malinowski, head of global communities at the company, said:
Okay, some mysteries shouldn't be mysteries. I can confirm that the new badge is actually the shape of a lynx.
The problem now, though, is that the Lynx School did not appear in either the original novel or the previous game, and in the fan-created setting, Lambert and Kayla Metz united with a part of the Cat School's Demon Hunters after the story of The Witcher 3 Wild Hunt.
