In 1968, two years after the cancellation of Mister Ed, at the age of 19, Bamboo began to suffer from a variety of age related ailments, including kidney problems and arthritis. He was euthanized in 1970.[citation needed]
A second palomino horse named Pumpkin (alternatively Punkin), which had posed for still pictures used in press kits for the show and some personal appearances, survived until 1979. After Bamboo Harvester's death, the second horse was unofficially known as Mister Ed.[citation needed]
By 1968, Bamboo Harvester was suffering from a variety of health problems. Controversy surrounds the story of his demise, and there are at least two separate versions of what happened, both from plausible sources which might reasonably be expected to have the correct story.[citation needed]
In one version, he was euthanized in 1970 with no publicity, and buried at Snodgrass Farm in Oklahoma.[citation needed] However, a different version was given by Alan Young. Young wrote that he had frequently visited his former co-star in retirement. He states that Mr. Ed died from an inadvertent tranquilizer administered while he was "in retirement" in a stable in Burbank, California, where he lived with his trainer, Lester Hilton.[citation needed]
Young says Hilton was out of town visiting relatives and a temporary caregiver might have seen Ed rolling on the ground, struggling to get up. Young said Ed was a heavy horse and he was not always strong enough to get back on his feet without struggling. The theory is that the caregiver thought the horse was in distress and administered a tranquilizer and for unknown reasons the horse died within hours. The remains were cremated and scattered by Hilton in the Los Angeles area at a spot known only to him.[5]
In this version it was a different horse that died in Oklahoma in February 1979 which widely thought to be Bamboo Harvester, but instead this horse was merely one that posed for the still pictures of "Mr. Ed" used by the production company for the show's press kits. After Bamboo Harvester's death in 1970, this horse was unofficially known as Mister Ed, which led to him being reported as such (including sardonic comments on Saturday Night Live'sWeekend Update) following his own death.[6]
Young said when the Oklahoma horse death story came out in 1979, he knew it was not the real Mr. Ed, but did not have the heart to "shatter their illusions" that the horse being memorialized was not the real Mr. Ed. He believes it was a horse used for early publicity photos.[5]
Whether or not it was the real Bamboo Harvester, the horse was laid to rest in 1970, on the farm at Snodgrass Farm in Tahlequah, Oklahoma, with no marker. It wasn't until summer 1990 when Mister Ed fans of Oklahoma dedicated a standing granite gravestone to honor the grounds of his grave, though the epitaph uses his stage name and image as 'Mr. Ed', and does not mention his death date of 1970.[citation needed]
