It may not be domestic… (though it not running away may indicate it is), but rather the descendant of previously released domestic rabbits… there was a whole big colony of them over in Bellevue for a while until they were relocated for construction. They were most definitely wild, but looked like pet bunnies because most of their parents were. I've also seen probable domestic and part domestic bunnies living in the colony by the bike path a little south of here too.
