VICTIM:
BULKIN, MALE MIXED BREED CAT

DIAGNOSIS:
CANCEROUS TUMOR (FIBROSARCOMA AND MAST CELL TUMOR)

"The microchip was found at the center of the mass."  - Bulkin's veterinarian, as quoted in the medical record

Fibrosarcoma "likely from microchip." - Bulkin's lab report

Summary
In February 2005 a male mixed-breed cat named Bulkin was implanted with a HomeAgain® microchip for identification purposes. Two years later, his owner detected a lump at the implant site. The lump was surgically removed in October 2007, and identified as a moderate grade fibrosarcoma (cancerous tumor). The microchip was found embedded within the tumor.

Bulkin underwent chemotherapy and radiation treatment for the cancer. He survived the ordeal.

On October 4, 2010, Bulkin's owner, Andrea Rutherford, filed a lawsuit against Merck & Co., and Digital Angel, alleging that the microchip caused the tumor. The plaintiff is requesting a trial by jury and reasonable compensatory damages.
