WINNIPEG, Manitoba (Reuters) - Canada's postal system has stopped delivering mail to a home in Winnipeg, Manitoba, after a mail carrier was scared away by a "very threatening cat," the Winnipeg Free Press said on Friday. A Canada Post spokeswoman said the agency was concerned about the safety of its carriers, although it hoped for an amicable solution to its dispute with cat-owner John Samborski. "The letter carrier who delivers mail there ... was brought up on a farm, she is very comfortable with animals," spokewoman Kathi Neal told the newspaper. "Apparently this is a very threatening cat." Samborski told the paper that his eight-year-old, declawed, black cat Shadow is docile, and it was "ridiculous" for Canada Post to make him to pick up his mail from a post office instead of delivering it to his door. Shadow "likes to eat and sleep and cuddle. You could drop a bomb and he'd just open one eye, take a look, then close them and go back to sleep," Samborski, 41, told the newspaper.
