World's longest cat dies - Telegraph Stewie's full name was Mymains Stewart Gilligan. Hendrickson bought him from a breeder in Hermiston, Oregon, in 2005. Last month, he attended the International Cat Show in Portland, Oregon. "He did really well at the show, even though he wasn't feeling totally perfect," said Valerie Horton, the show's entry clerk. He loved being there because he loved the public. He always did. Officials for Guinness World Records did not immediately respond to inquiries about a successor to Stewie's record. The previous record-holder, Leo, a 48-inch-long Maine Coon owned by Frieda Ireland of Chicago, died several years ago. Stewie was diagnosed in early 2012 with Lymphosarcoma, a malignant disease of the lymphoid tissues. He responded successfully to chemotherapy and was declared cancer-free, but the remission period was brief and a vet recently found another, more aggressive tumour on his kidneys, Hendrickson said. "I knew that although we could fight it, the end was near and so I wanted to simply make him comfortable and let him enjoy the time he did have," she said.
