Abstract: A pet strap formed of a transparent material, such as plastic or synthetic rubber, with photoluminescent or phosphorescent colored pigment homogeneously dispersed within and incorporated into the elastometric material. The preferred photoluminescent is strontium oxide aluminate or strontium barium aluminate, which emit a yellow-green light. The strap may be disposed to encircle the neck of the pet as a conventional collar with a buckle and strap end retainers. The strap may also be made in various dimensions suitable for pets of all sizes, and may be configured to be trimmed to the desired size. Another embodiment of the pet strap includes a light reversion strip and an underlying or encased fabric reinforcing strip encased within the elastomeric strap adjacent the bottom side of the strap that contacts the pet. The light reversion strip will allow available light to charge the luminescents more proficiently for better performance.
