The injured 8-week-old kitten was first spotted in Massapequa on July 20, while All About Spay Neuter was working with a Sunset Boulevard resident on a Trap-Neuter-Return (TNR) project.
The kitten was trapped on August 2 and taken to a veterinarian, where the pellet gun wound was discovered.
Due to the nature of the injuries, the kitten had to be euthanized.
