Ed's Death
didn't he die of neglect and poor treatment?
shareFrom Wikipedia:
By the time Mister Ed reached the age of 19 he was suffering from a broken leg and a variety of health problems, and in 1970 he was quietly put to sleep with no publicity. A horse that died in Oklahoma in 1979 (which was widely reported to have been Mister Ed, including sardonic comments on Saturday Night Live's ersatz news segment) was in fact an animal that once posed as Ed for publicity photos used by the production company.
