Abstract

Claims19
An imaging device comprising:
- a) a base layer;
- b) an attractant material, said attractant material operatively associated with said base layer for inducing an animal to lick said base layer;
- c) indicia, said indicia disposed on said base layer and formed from a first material that is not substantially visible;
- and
- d) a colorant, said colorant provided on said base layer and formed from a second material adapted to be water soluble, said second material when made soluble will not adhere to said first material whereby when an animal attracted to said device is induced to lick said base layer and cause said second material to become soluble, said soluble second material is distributed across said base layer rendering said indicia visible.
