the news happend to be playing the the TV just now and I heard a story about something that happend, a man had fallen while going from his wheelchair to his bed and could not get up, 10 minuts later there was a knock at his door and teh police shouted that they were the police and was something wrong..he shouted back, that yes he has fallen and cant get up but how did they know that, they sid that they recieved a call from his apartment...turned out when the guy fell his cat turned on the speaker phone and pressed the pre programmed 911 key..the man said he had attempted to train his cat to do this before but never thought it would actually work!
