  / "We report here our experimental        \
  | demonstration of flexible egocentric     |
  | tooling in a pet cow (Bos taurus),       |
  | Veronika, who uses a deck brush to self- |
  | scratch. Across randomized trials, she   |
  | preferred the bristled end but switched  |
  | to the stick end when targeting softer   |
  | lower-body areas. This adaptive          |
  | deployment of tool features reveals      |
  | multi-purpose tool use not previously    |
  \ reported in non-primate mammals."       /
